FINDING LOST MANHWA

I keep forgetting the name of this manhwa but basically there's this brownhaired blunt male writer who goes to uni, he's the uke, and the seme is white haired. He is fake nice to keep up with appereances or smth I forgot but he's kind of an asshole to push the writer away and the writer doesn't let him thing is writer needed to write something and while this relationship was going on he didn't tell a thing to white haired guy so white haired guy finds out big mad, breaks up with him. Then years later they meet again on a film production set idk I forgot. Much appreciated
