I didn't read the manga at that time so I only remember the cover. There was a boy, probably a high schooler, with wavy blond hair looking at the front. The main lead wasn't fully shown on the cover and I'm pretty sure he had short, black hair. I remember some panels and it seemed like the mc (blonde) never really smiled and was often uneasy while the ml (black hair) was really cheerful and maybe played basketball too (still not sure T-T).
