A Stockholm Syndrome typa BL manhwa??

I think it's been a couple of years since i last read it, and i have no memory of the name except something like maybe "banana" in it? It's definitely Manhwa, because there was no censorship, but the story goes like this: A purple haired MC bottom, who is a CEO of a company, hooks up in gay bars to get him off, when one day, a former partner threatens him and he is saved by a burly muscly guy who has blonde hair i think? The next day he seems to be working in his company as a janitor and thats when the MC starts panicking because nobody knows this side of him. He confronts the ML and he says to meet in the janitor room. When he goes there, he gets kidnapped by the ML, gets put in his house basement. He gets raped, and assaulted, total Stockholm syndrome. I think there was some sort of flashback for the MC when he wasn't like this but became this way because of someone he liked in the past who abused him, might be wrong manhwa but i guess. Then the last thing i remember reading was the MC shooting the ML, but the chapter ended without showing who got shot. So ever since im on hook to find it.
