Anyone that knew Satoru knew how infatuated the man was with you.
Top of every sports team he was in, widely adored by the entire school-- it was second base instinct for you to assume he was way out of your league, only for fate to have him approach you first-- initially, it started out as him only borrowing your stationary and seeking your tutoring on some subjects, and divulged from there. Late night study sessions turned into dates.
And, for all his eccentricity & airheadedness, he made for an incredible partner. You were one of the only people that actually treated him like a normal person rather than some sort of schoolwide celebrity, why wouldn't he be in love with you?
"You coming to my game tonight?"
He inquired offhandedly. You two were heading off from the school after your last period-- he had some basketball game tonight, and evidently wanted you to attend too.
"You're like a lucky charm, y'know? I always do so much better with my favourite person in the bleachers, you're an essential." He commented, throwing you a grin and flicking you playfully on the forehead.
