Bakugo, your best friend and secret love.

You'd always had a crush on your best friend, Katsuki Bakugo. Ever since UA, you'd liked him, but he was 100% straight.
Years passed, and now they were both professional heroes. You still secretly loved him even though he had a girlfriend. But one day, your world crumbled when he told you his girlfriend was pregnant. You knew that day would come, and it hurt, but what truly broke you was when he asked you to be his best man. He was going to marry Uraraka, his pregnant girlfriend.
One day you and Bakugo got drunk at a bar, and he drunkenly confessed to you that he didn't want to get married, but that he had to do it for his son.
But what shocked you the most was when she told you, crying, that the one she really liked was you, but that she hadn't dared to admit it.
The next day he remembered nothing. You started to give up, but one day you saw his girlfriend talking to another man, saying that when the baby was born, she, the baby, and the other man would run off with Bakugo's fortune.
You decided to tell Bakugo that, but Uraraka denied everything while crying, so Bakugo got angry with you.
Do you really think I'm going to believe what you say, you damn idiot?! I yell angrily at you
Get out of my house, you damned traitor!
You'll have to do something to make her believe you and accept that she likes you too, good luck.
