My eyes shot wide open as I realized what I was doing. "M-Mmm... What's this feeling?" It was soft and warm, but as the fog of sleep lifted, I realized that I was touching something that I shouldn't be.
My heart started racing as I heard a soft moan. I immediately pulled my hand back and sat up, my face flushed with embarrassment. "I-It's... Yui-san's breast...!?" I muttered to myself, feeling my cheeks burn. Wait, how did she get in here again? And why is she in my bed?
Then it all came rushing back to me—the scenario from last night. Yui had asked if she could stay beside me, and I had agreed, but this... I never expected this to happen.
I quickly got out of bed and moved to a safe distance making sure there was enough space between us.
I couldn't believe I had accidentally done something so inappropriate.
"I-I'm so sorry, Yui-san," I stammered, trying to find the right words. "I didn't mean to... I mean, it was an accident..."
She stirred slightly, her eyes half-open. "Mmm...? Kousei-kun? What's wrong...?"
"I... I accidentally touched your..." My face was now bright red, and I could hardly bring myself to say it.
"Hm...? Touch what?" Yui asked, looking a bit confused.
I took a deep breath, trying to calm myself down. I couldn't bring myself to say it out loud. My face turned even redder as I looked away. "N-No, it's nothing... Just forget about it..."
But Yui's expression told me that she had figured it out. Her face turned beet red, and she looked down, trying to hide her embarrassment. "K-Kousei-kun... D-Did you..."
"No, I did- I mean... I... Did..." I stammered, feeling utterly mortified.
Yui glanced back at me, blushing just as much. "I-I'm sorry... It's my fault."
"N-No! Actually, it's my fault too..."
She let out a soft sigh. "Let's just forget about it, okay? Accidents happen..."
"Yeah... You're right."After a moment of awkward silence, I walked out of the room and headed to the bathroom to wash my face, trying to collect my thoughts after that embarrassing moment.
Just then, Nazuna opened the door to the bathroom and looked at me with a serious expression. "Onii-chan... Let me tell you something. I had a dream last night."
"Nazuna...? What is it?"
"Yesterday... Yui-chan came to our house."
I stayed silent, looking at her with surprise. "...Ummm... Look behind you."
"Hm?"
Nazuna turned around, and her eyes widened when she saw Yui standing there with a smile.
"Good morning, Nazuna~"
Yui greeted her cheerfully.
Her eyes widened even more. "O-Onii-chan... I-."
"It's not a dream."
"SO IT'S TRUE THAT YOU TWO ARE TOGETHER!?"
"H-Huh!? Where did you hear that!?"
"Y-Y-Yui-chan said that you two are going out!" Nazuna replied, pointing at Yui, who blushed and looked down at the floor.
"I believe there's some explanation I have to do..." Yui said softly, feeling a little embarrassed herself.
And so, I took a deep breath and explained everything that happened from the beginning, including how we got into the pretend relationship.
"So it's just a pretend play huh... But... Why him? There are more boys out there who are much more suited than you, unlike my Onii-chan who just lazes around."
The emotional arrow that Nazuna's words pierced me deeply.
Yui, however, remained calm and composed. "I may not be the most impressive or accomplished person, but I care deeply for your brother, Nazuna," Yui said gently. "And I promise you that I will do everything in my power to make him happy and support him in whatever he chooses to do."
Fine... Fine... I feel like a villain here, but..." Nazuna stayed silent. "I think you guys should end this pretend play asap... because." Nazuna looked at me. "If you guys still do this kind of pretend play longer... You two might end up on a bad ending."
"Bad ending?" I tilted my head in confusion.
"Onii-chan, you're really dense, huh? What if someone who likes you ended up seeing you with Yui-chan... especially if Yui-chan is an IDOL... There will be scandals about her, and she will end up being turned down."
She had a point, and I didn't want Yui to face any problems because of our pretend relationship.
But just then... there was a knock on the door. "I'll open the door." I stood up and walked to the door, slowly opening it. "Hello..." I looked up at the person standing there.
She was dressed in a black suit and exuded a pleasant perfume scent. She was also a good-looking woman.
"U-Ummm, is there something you need?"
She stayed silent for a bit before speaking. "Is Yui here?"
"E-Eh? Who are you?"
She sighed. "My name is Masatsuki Chika, I am... Yui's mother."
"...Eh? Yui-san's mother...!?"
