While Shishio hadn't said a single word to Yukinoshita's big sister, he could see a big difference between Yukinoshita and her big sister.
The chest size was one thing.
However, if Shishio had to say their biggest difference would be how they presented themselves.
While Yukinoshita appeared cold and detached, making her appear like a beautiful flower on the cliff of the snowy mountain, she was a kind and gentle girl. She was also a cat maniac, and as long as they knew her, and she also knew them, she would talk with them warmly.
On the other hand, Yukinoshita's big sister appeared so close and smiled warmly at everyone. However, she was detached and wouldn't let anyone get close to her.
Shishio knew that it was quite rude for him to say this, but frankly, he didn't really have much interest in Yukinoshita's big sister since there was something that he needed to do now.
"Senpai, I'm so scared!"
Yukinoshita was dumbfounded when she was hugged so suddenly. "Wa-Wait, Shishio-kun! Don't hug me so suddenly!" However, while she showed resistance, she didn't show that she hated this intimate contact.
"Sorry, I appeared so pathetic," Shishio apologized, but he still hugged Yukinoshita's waist. Her waist was so slender he wondered whether she had eaten enough. "A group of people in a black suit suddenly came and surrounded me. I thought they were planning to do something bad."
Yukinoshita glared at the men in black suits menacingly.
'Hello?!'
The men in the black suits had a cold sweat on their backs when Shishio slandered them!
'Scared?'
They couldn't see the fear in Shishio's eyes since this guy had been so relaxed even if they surrounded him.
"Sorry, it's my big sister's fault."
"No problem, I feel better now."
"...How long are you going to hug me?"
"Can I stay longer?"
"No!" Yukinoshita blushed and slapped Shishio's head. "Don't get too brazen! There are so many people here!"
Shishio wanted to tease Yukinoshita, but he knew that this wasn't a good place since there were so many people. He rubbed his head and said, "Senpai, don't hit my head. What if I get a concussion?
"You're wearing a helmet! How can you get a concussion!"
"Cough! Cough! Yukino-chan, while I'm happy to see you having fun, it isn't good to ignore your big sister, you know?" Yukinoshita's big sister then looked at Shishio and asked, "Also, why take off your helmet and introduce yourself? Isn't it rude that you don't say anything to your sister-in-law?" She stared at Shishio with an emotion of worry and curiosity with a half-half ratio.
Shishio didn't say anything at first and looked at Yukinoshita.
Yukinoshita gave him a nod and said, "Nee-san, this is Shishio Oga, and he's..."
"Your boyfriend?"
"My friend."
Yukinoshita corrected her big sister's mistake.
Shishio also took off his helmet and gently greeted Yukinoshita's big sister. "Hello, Nee-san. My name is Shishio Oga."
"...Hmm... a friend, eh?"
Yukinoshita's big sister moved closer, observing Shishio from a close distance, ignoring her little sister's displeasure.
Shishio was unfazed even though he was being stared at and only stared at Yukinoshita's big sister back.
Yukinoshita's big sister suddenly smiled and said, "I like it when you call me, Nee-san. You can call me that."
"...Okay." Shishio nodded and didn't think too much, then looked at Yukinoshita.
Yukinoshita noticed Shishio's gaze and said, "Nee-san, can you go back? I'll go with him."
"Eh? Are you going somewhere? Can you bring me with you too? I'm also curious about Shishio-kun!" Yukinoshita's big sister quickly looked at the two with excitement before looking at Shishio with a begging expression.
"Sorry, Nee-san, but I don't know your name."
"Oh, right! I forgot to tell you my name." The young woman showed a beaming smile as she introduced herself. "My name is Yukinoshita Haruno. If you do well in front of me, I can acknowledge you as my brother-in-law."
"Nee-san!" Yukinoshita blushed and wanted to tell her sister to shut up somehow.
"While I want to say that I want to invite you together, you should ask Yukino-senpai's opinion first whether she agrees or not," Shishio said and left the decision to Yukinoshita since he wasn't really sure about how close the relationship between the two.
After all, not everyone could be like Ayaka and Nana, right?
"Come on, Yukino-chan! Let me go with you!" Haruno quickly moved closer to her little sister while begging.
Yukinoshita let out a long sigh and said, "While I don't mind, are you okay with spicy food?"
"Spicy food?" Haruno was surprised and asked, "Since when did you like spicy food?" She suddenly realized that she had asked a stupid question and looked at Yukinoshita and Shishio back and forth. "Ah, I see, but I'm alright with it. Are you going to eat Korean food like before?"
"......."
Yukinoshita and Shishio understood where Haruno had seen them.
"No, we're going to try Thai food."
"Oh? I'll go! I'll go!" Haruno then looked at Shishio with a smile and said, "Shishio-kun, why don't you enter the car? I want to talk with you more."
Shishio looked at Yukinoshita, who gave him a nod. He nodded and said, "Okay, but I'll keep my motorcycle inside. Is that okay?"
"Sure." Haruno nodded and said, "Why don't you just give your motorcycle to my bodyguard first?"
"Okay." Shishio stepped down from the motorcycle and gave the key to Haruno's bodyguards while wondering how rich Yukinoshita's family was.
The three entered the car together while Shishio told the address of the Thai restaurant where they would eat.
The driver knew the address and left everything to him.
Shishio sat next to the driver while looking at two sisters through the rearview mirror inside the car.
"What's wrong, Shishio-kun? Do you have something to ask?" Haruno asked with a grin on her face.
Yukinoshita didn't say anything and only coldly looked out the window.
"You two have a bad relationship?" Shishio asked.
"....." Yukinoshita and Haruno.
Haruno laughed, and Yukinoshita let out a long sigh.
"Why do you think so?" Haruno asked with a smile.
"No, it's just that you two don't fit with the description of a good relationship as a sister." Shishio shook his head and thought that a sibling relationship was different from one to another. It might be because the age difference between Haruno and Yukinoshita wasn't that far, making him feel they were like a rival.
"Oh? What kind of relationship should we have as a sister?" Haruno asked curiously, and it also piqued Yukinoshita's curiosity.
"Well, your relationship is different from two sisters that I have seen before."
"Oh? What kind of relationship do they have?"
"Well, little sister often acts spoiled at the big sister such as asking to clean up the ear, hugging each other, and sleeping together, probably? Not sure, though." Shishio somehow couldn't imagine Yukinoshita asking Haruno to clean her ear or go bathe together, though.
Haruno smiled brightly, hearing Shishio's words, then looked at Yukinoshita excitedly. "What do you think, Yukino-chan? Do you want me to clean up your ear, take a bath together, and sleep together tonight?"
"If you want to dream, keep it when you're sleeping!" Yukinoshita gnashed her teeth and looked at Shishio. "Also, don't say something stupid, Shishio-kun."
"Okay, okay."
Shishio could tell that Yukinoshita's mood wasn't good, so he didn't really tease her anymore.
Still, why was their relationship so bad?
Haruno smiled and said, "Sorry about that, Shishio-kun. She's always like that."
"No, it's alright. I think that part of her is charming, though," Shishio said nonchalantly.
"......" Yukinoshita looked away, looking at the window, and didn't want to let her big sister see her expression.
Haruno whistled happily and said, "Big sis is so happy! Let me treat you later!" She leaned forward and hugged Shishio without hesitation.
"Nee-san!" Yukinoshita quickly pulled Haruno, so this woman wouldn't get so close with Shishio.
While there was a difference on their chests, without a doubt, they were sisters, especially when they smelled so good.
Shishio glanced at the two sisters for the last time before he continued to guide the driver since this guy almost made a wrong turn.
While Shishio was talking with the driver, Haruno glanced at Yukinoshita sneakily and asked in a whisper, "Yukino-chan, is he your boyfriend?"
"No." Yukino curtly answered in a dry manner.
"Then can I take him?" Haruno asked with a smile.
Yukino only looked at Haruno for a moment and let out a tired sigh. "Enough of this charade, just what do you want?" She had planned to eat dinner with Shishio, but her good mood was thrown away because of her big sister.
"I'm just curious since I saw you with someone before, but I never expected that you would have a boyfriend." Haruno moved even closer and asked, "Have you told mom?"
"As I said, he isn't my boyfriend, and it has nothing to do with mom." Yukinohsita looked at Haruno with a frown.
Yukinoshita didn't really want to talk with Haruno, but how could Haruno let Yukinoshita go?
"Then should I tell our mother?"
"...No." Yukinoshita could imagine what kind of problem might appear if Haruno told her mother, so she didn't really want to.
Haruno smiled and said, "Then leave everything to your big sister. I won't do anything bad since I just want to know what kind of boy has conquered my Yukino-chan."
"As I said, he isn't my boyfriend!"
"He isn't your boyfriend, but you let him hug you?" Haruno sighed and said, "Yukino-chan, I know that you're shy, but you need to be honest sometimes, you know? Don't you feel afraid that you're hurting his feelings?"
"....." Yukinoshita gave up talking since she knew that no matter how she talked, Haruno wouldn't believe her. However, she didn't feel surprised since she knew it might be her first time to have such an intimate action with a boy.
"We're about to arrive at the restaurant."
Shishio suddenly interrupted, and Haruno's attention also turned toward Shishio. "Okay! By the way, it is my first time having Thai food, Shishio-kun. You can be the lead, right?"
"Okay, Nee-san." Shishio honestly nodded.
Haruno laughed and said with a sweet smile, "It's good that you're an honest kid, Shishio-kun." She then looked at Yukinoshita and whispered, "Isn't he a good kid? Simple and cute."
"..."
Yukinoshita glanced at Haruno for a moment, then looked at Shishio, thinking that this guy's scumbag ability was so amazing.
As they arrived at the restaurant, Yukinoshita and Haruno looked at the restaurant for a moment before they entered together.
The exterior of the restaurant was quite sketchy, but the inside was unexpectedly clean and neat.
While there were guests, there weren't many people inside, so the three quickly gathered everyone's attention.
However, no one talked to them since this is how the people in Tokyo were.
Still, it didn't mean that the people inside the restaurant couldn't appreciate them since the three were so eye-catching.
The staff gave them a menu order, and Haruno and Yukinoshita looked at it curiously.
Shishio looked at the two sisters in front of him and smiled gently.
"What?" Yukinoshita looked unhappy at Shishio.
"Nothing." Shishio knew that Yukinoshita would be embarrassed if he reminded her what they were doing, so he just kept quiet and let them be close to each other naturally.
Yukinoshita looked at Shishio in doubt, but she didn't continue to pursue and continued to look at the menu curiously.
Haruno looked at Shishio with a smile, but she didn't say anything and continued to talk with Yukinoshita about the menu since it was a rare chance for her to spend her time with her sister.
Yukinoshita also subconsciously answered since she was quite curious about the Thai dish.
While the name of the menu was unfamiliar to them, there was a description of what kind of dish it was, so they could imagine what kind of dish that would come out.
However, it was harder than they had thought.
While two Yukinoshita sisters were talking about the menu, Shishio thought even if their relationship seemed bad, they were still a sister after all.
"I give up." Haruno looked at Shishio and asked, "Shishio-kun, can you be the one who orders?"
"Sure." Shishio nodded and asked, "But, you're really okay with spicy food, right?"
"Okay, I'm alright with it." Haruno patted her chest.
"Don't cry if you can't eat it," Yukinoshita curtly said.
"Oh? Yukino-chan, are you going to challenge me? If someone gives up eating the spicy food that is ordered, they'll have to follow one request of the winner," Haruno said with a smile.
"Okay, I'll wipe that composure on your face later." Yukinoshita agreed without hesitation.
"By the way, you also need to join the competition, Shishio-kun!" 2x
Haruno and Yukino said at the same time while looking at Shishio.
"...."
Shishio looked at the two and thought that the relationship between the two sisters was really good.
