so like there was this manga i read when quarantine just started and i want to reread it but i cant find it. it was about two guys who go to the same school and they were kind of enemies, one of them was an athlete i think he was tennis player(?) and then the other guy was a smart guy not really nerdy but he had glasses. the athlete had black hair while the smart guy had blond hair i think. the smart guy is jealous of the athlete cuz he used to be the hearthrob but then the athlete came and stole his spotlight. then the athlete was being chased by some girls and the smart guy helped him and pulled him in a room then smh they ended up kissing and that kinda became a regular thing for them tho they still "hate" each other when they arent doing stuff

also if u guys know a manga abt 2 guys hating each other then ending up together please tell me

Hey, I’m looking for some doujinshi/yaoi. I remember that the seme has black hair and I think that he's a doctor or something like that, and that his name start with a H.
The uke is more smaller than the seme and he is in high school.
I remember that :
-the seme took the uke in his car, and they went to the beach (And sex in the car ??? Maybe I’m not sure)
They had sex with some sex toy(s?) in a hotel room

Thanks you
