I forgot the name of this manhwa

This manhwa is fully-coloured and based off school-life in Korea, I know very vague things about this manhwa but if anyone knows the name please tell me, ok so I believe the mc has red-hair and a younger sister, the mc has a bestfriend as well which has glasses? (I think) anyways, the mc has a crush on a guy, this manhwa is a bl but I think it’s a shounen ai genre, anyway this guy has a important role in the class? like class president or something, or maybe he’s in charge of some club? people wanted to join the club to skip classes or something, anyway I think because so many wanted to join I think there was some lucky/random choosing anyway.. the mc didn’t get chosen and he’s devastated because he wants to get closer to his guy crush (pretty sure his guy crush has black hair) anyway his bestfriend gets chosen and offers to switch/let him in the club instead?? man, I don’t know, thanks in advance if anyone knows the name.
