Help me find this one

It was ongoing, but i don`t remember the title, so i will describe as much as i can remember.

It starts off as being the MC`s birthday, but he is alone and his bestfriend, who is an pop idol is out working or smth. He then attracts a guy, which he sleeps with and leaves. The MC is then arrive home and turned out his best friend came home early with a birthday cake, and becuase he was out at a hotel, his best friend is angry and forces him to eat the cake. Fast forward, The MC bonds closer with the one night stand dude, and the MC`s best friend doesn`t trust him. He comes over to his house, the mc is actually a manga artist, and the best friend comes home and they meet? I don`t remember the next part, but the MC and one night stand guy break off their relationship, and the MC and bestfriend form a relationship, bc the MC actually has a crush on him. Turns out, the MC looks for him at a drinking party, and his bestfriend has cheated on him with a black haired girl and he reveals that he never actually loved the MC.

I ditched it because it was ongoing and i couldn`t be bothered, but its been like a year since i`ve read it and i want to know what happens. Thankyou!!!
