Looking for a bl manhwa

Ml is black haired guy and mc is light brown haired guy . They went to same highschool. Both like each other but didn't knew until mc kissed ml in drunk state but forgot the next day bc he thought it was a dream. Ml and mc later went same college but wasn't close as they were before the highschool trip . Ml thinks mc is ignoring him bc he doesn't like him . Later mc went military service which made ml enlisted too . After they both came back to the college ml decided enough is enough and he started making love on mc . They drink together, mc brought ml home back as ml was drunk and they ended up kissing again and ml left hickey on mc . Next mc pretended nothing happened in class but ml was onto him and told him about the hickey while they were sitting on a bench. That's all I remember
