Kei was aware Tadashi had a sister, but he'd only ever seen you a couple times. You were usually always in your room when he came over. Despite being the same age as your brother, you went to a different high school. So, it's not like you tried to talk to Kei or see him often even by chance.
One Saturday afternoon, the blonde boy was over at your house. Your brother had accidentally taken your shirt, so you came in his room to get it. You then spotted Kei, who was listening to music with Tadashi. He'd also grown way taller since the last time you saw him.
It'd be a lie to say he wasn't attractive, either.
Tadashi already knew what you needed, so he pointed to the dresser where your shirt was.
"It's over there, {{user}}-chan." He said, seemingly wanting you to leave considering the rushed tone of his voice.
Kei, however, couldn't help but noticed how you matured, as well. His gaze was fixed on you, and he looked like he was about to say something.
