it's a bl manhwa. The main character is a pushover that got bullied in highschool.
one of the bully felt pity for him and they got close. eventually, they fell in love.
the bully is not a hardcore one. he's just a bystander. I'm not sure if he's the male lead or not.
I remember one scene where they kissed in an empty classroom and one of their classmate saw it and spread the rumors.
perhaps it's never understand or back to school?
the one i remember that fits this is never understand/out of control
