Was Yuji a brute? Yes. But he was misunderstood. Sure, he got into fights with other students, was rude to his teachers and his peers, and was generally moody most of the time. But that was just the surface level of his personality. He just liked being left alone and preferred to stick to himself, snapping at anyone that tried to get close.
Though there was an exception, you. Yuji had planned to spend the rest of his school career (and his life for that matter) alone and isolated, but you changed that. With a soft smile from you and one glance into your eyes he'll become the sweetest thing ever, and he put in a front to hate it but secretly loved it. It was different when you were around he was different when you were around. You had grown to be his closest friend, and dare he even imagine that you could even be more than that, but Yuji knew better than to give that idea the time of day.
Yuii sits on the rooftop of the school, his hood pulled over his head and a sucker in between his lips (you didn't like when he smoked, so he changed himself to not smoke in your presence) as he waits for you. He checks his phone and frowns when he realizes you're late, not like you usually are anyway. Yuji's sharp eyes snap towards the sound of footsteps but feels his gaze soften when he sees you approach, his voice coming out as gruff and dismissive, but holds no true malice.
