After that small incident, everything was normal. Izumi spent the whole day in class without a problem.
A chime can be heard in the room, signaling the end of classes.
Hearing this, Izumi got up of his seat and went straight towards the door.
As he walked in the corridor, he suddenly felt somewhat thirsty, so he made a detour and went towards the back of the school.
Izumi went there because the back of the school is where the closest vending machine is located.
After arriving, Izumi chose a drink that he like as he inserted money to the vending machine.
After a few moments, Izumi grabbed his drink and decided to leave, when suddenly, he heard voices near him.
Since he has nothing else to do, Izumi went towards the source of the voice. But when he saw what was happening, he immediately hid behind the wall. But although he was hiding, he was still observing the situation.
What was in his field of vision was his younger sister, Nikaido Yuuna. And standing before Yunna was a somewhat handsome first year high school boy. And from the looks of it, it seems like he is confessing his love towards Yuuna.
"Yuuna, I love you. Please go out with me." The somewhat handsome boy said with a smile.
"So-sorry, I can't go out with you." Yuuna replied with a stutter, averting her eyes.
(Woah, this is the first time I see that sister of mine becoming meek and timid.) Izumi thought in his mind as he watch them.
"Why!? I'm handsome! My grades are high! We are a perfect match!" the somewhat handsome boy protested as he grabbed both of Yuuna's shoulders, a creepy smile appearing on his face.
(Wow, this is the first time I'm seeing a somewhat handsome but creepy obsessive guy with a personality similar to a stalker in real life! I thought someone like him would only exist in novels or mangas.) Izumi thought, his eyes wide open.
"S-stop..! You're hurting me..!" Yunna said with a pained expression.
"No... not until you agree to go out with me.." the somewhat handsome but creepy boy said in a very creepy tone.
(What the heck. that's creepy, dude, stop it. Oh wait, isn't this situation going in a really bad direction?) As Izumi thought that, he showed himself from the two of them.
"Hey, hey.. Why are you two so loud? I can't concentrate to buy my chocolate milk at the vending machine over there if you're making this much noise!" Izumi said in a very irritated tone as he sip his chocolate milk that he bought in the vending machine.
"B-big brothe... Izumi.." Yuuna whispered quietly.
"And you, that creepy dude over there. Yuuna clearly said that she doesn't like you, so get the heck out of here." Izumi said, not bothered to look at Yuuna at all.
(Uhh~ this is so troublesome! Why do I have to save this girl!? She causes nothing but trouble! If she's not my sister, I wouldn't even bother saving someone like her.." Izumi thought with a deep sigh.
"You! Who are you!? Don't interfere!" the creepy boy said in a loud voice.
"Me? Well, I'm that girl's brother." Izumi said as he pointed his hands at Yuuna.
"You liar! Yuuna said she only has Yuu as her brother!" The creepy boy said with a trace of ridicule.
"Wha-!" Yuuna was flustered when she heard the creepy boy.
(What the f*ck. Judging from her reaction, what that creep said must be true. That's just going too far. Nah, I'm out of here. I'm not her "brother" anyway. She said it herself.) Izumi thought with a frown on his face.
Seeing his expression made Yuuna scared and nervous.
"W-wait! Izu- Big Brother! No, I didn't mean to say any of that!" Yuuna protested in a loud voice, trying to explain herself.
However, Izumi only glanced coldly at her and left.
"Hey you! Do you think you can just barge in here and leave!?" The creepy boy shouted as he ran towards Izumi, preparing to punch him.
However, just as his fist are about to hit, Izumi dodged. "Wha-!" the creepy guy said in surprise.
Without any time to waste, Izumi immediately punched the creepy boy's face, and then instantly kicked his stomach, sending him flying. Then, the boy passed out.
"Ah! Th-thank you, b-big brother! A-and sorry for tr-" Yuuna said while stuttering. She bagan calling Izumi as 'big brother'. However, before she could finish her words, Izumi stopped her.
"Oh, okay." Izumi said coldly as he left.
Yuuna could only watch his back as he walked farther away, her eyes in tears.
°°°
(Ha~ that was exhausting. I'd like to see Mi-chan as soon as possible. Only her can recharge my energy.) Izumi thought as he walked on the road.
After that, he decided to wait for Mitsumi near the park.
After a few minutes, he saw Mitsumi walking at the distance. Seeing this, Izumi immediately ran towards Mitsumi's direction.
"Hey! Mi-chan! I was waiting for you!" Izumi said with a cheerful smile.
However, Mitsumi just walked past him, not even bothered to look at him. It's the same treatment he got from Mitsumi before they started dating.
(WHAT?) Izumi was surprised when Mitsumi ignored him.
"Wait, Mi-chan! Why are you ignoring me?" Izumi asked in a nervous tone.
However, Mitsumi still ignored him. Izumi tried talking to her a few more times, but Mitsumi didn't stop walking.
"Wait, Mi-chan! Could you please tell me why you're ignoring me." Izumi asked with a confused expression as he grabbed her hand.
Finally, Mitsumi looked at him with a glare and replied "Oh, Why don't you go see your 'Yukina' then."
"Wha-" Izumi was surprised after hearing her, then immediately said "It's just a misunderstanding, Mi-chan! You see, I saved her this morning! She just wanted to thank me!"
"It doesn't look like it to me though." Mitsumi said coldly.
"Ofcourse not! I love you, Mi-chan. I would love anyone other than you!" Izumi said.
"Oh? Then prove it then. Do you know how painful it felt for me to see you talking intimately with other women?" Mitsumi said in a cold tone.
(Wha-! So Mi-chan was just jealous.. that's cute! But I love Mi-chan. So I'll resolve myself.) Izumi thought.
"I don't know how painful it felt for you, Mi-chan. But if you said you felt pain, then I'll feel pain too!" Izumi said with a serious expression and immediately grabbed a pen he put earlier on his pocket. Then, he stabbed it on his palm before Mitsumi could even react. He stabbed his palm more than one time
"Wait! Stop it!" Mitsumi immediately took away the pen, but she was too late. Izumi's palm already has blood gushing from it.
Mitsumi made a very sad expression after seeing him.
"Why did you do this to yourself, stupid..!" Mitsumi said as she leaned on Izumi's chest.
"Mi-chan, don't be sad! This is just punishment to myself for making you angry!" Izumi said as he tried to calm Mitsumi down.
(Why is Mi-chan sad!? I thought she would be happy! Seeing her sad makes me sad too.) Izumi thought.
"You don't have to hurt yourself, stupid. It was my fault for being jealous in the first place.." Mitsumi said in a sad tone.
"No, it's my fault, Mi-chan. Let's go to the park to calm down first."
After that, they went towards the park.
°°°
At the bench on the park, Izumi and Mitsumi were sitting next to each other. Mitsumi was wrapping her handkerchief on Izumi's hand.
"Mi-chan, stop. My blood is going to stain your handkerchief at this rate." Izumi said nervously.
"It's alright. But I have one condition." Mitsumi said as she looked at Izumi.
"What is it."
"Walk with me on the way to school starting tommorow." Mitsumi said.
"But didn't you say that you'd get embarrassed?"
"Being embarrassed is better than have you interact with other girls so early in the morning like today." Mitsumi said with a teasing grin.
"Haha, I truly love you, Mi-chan." Izumi said with a smile.
"I love you too." Mitsumi replied with a gentle expression.
The park was empty, only the sound of leaves hitting each other because of the wind can be heard.
Izumi and Mitsumi stared at each other for a moment.
Then, as their face moved closer to each other, they closed their eyes. Their lips are going to connect.
And they kissed.
The soft and warm sensation can be felt by both of them.
"Hmm~.."
Then, after a few moments of being connected, they separated their lips from each other.
As they looked at one another, their faces turned red.
"T-that was my first kiss.." Mitsumi said softly as she touched her lips.
"T-that was my first kiss too.." Izumi also said as he touched his lips, still remembering the soft sensation he felt.
Then suddenly, Mitsumi got closer to him and began kissing his neck. When she moved away, a red mark can be seen in Izumi's neck.
"W-what was that, Mi-chan!?" Izumi was surprised by Mitsumi's sudden action.
"Shio s-said that she saw something on the internet, she said that people mark the things they own. Y-you're mine, so I placed a mark on you." Mitsumi said shyly, her face turned even redder.
Izumi blushed after hearing her said that. Then, he smiled gently.
"Okay, from now on, I'm yours, Mi-chan." Izumi said. He then suddenly kissed Mitsumi's neck, leaving a red mark, and after that, he said "And you're also mine."
"Yeah, we both own each other." Mitsumi said with a gentle expression.
°°°
After that, both of them went home. When Izumi walked inside his house, he saw Yuu sitting on the sofa, Yuuna was clinging at his arm.
"I'm home." Izumi said with a smile.
When Yuuna saw him, her face expression became conflicted.
"Welcome home, bro. You seem happy today." Yuu said.
"Yeah, I guess you could say that." Izumi said with a smile.
When Yuuna heard Izumi say that, a relieved expression appeared on her face.
Izumi continued walking after that.
"Hm? Hey bro, what's that red mark on your neck?" Yuu said, noticing the mark Mitsumi left.
Yuuna's eyes also widened after seeing it, and a somewhat dejected look appeared on her face, but Izumi didn't notice it.
"Ah-! Well, this is just a mark my girlfriend left on md, Ahaha." Izumi said, thinking that there's no point in hiding his girlfriend to his siblings anymore.
But hearing him say that made Yuuna sad. Izumi didn't notice it though.
"Woah, you have a girlfriend, bro!? How nice~" Yuu said.
"Hahaha, I know right?" Izumi said with a laugh.
He then continued walking straight towards his room.
Meanwhile, Yuuna was watching his back with a sad expression.
