Does anyone remember this bl manhwa, if u do, pls tell me huhu I forgot the title it's a very clumsy guy (with red hair I think??? Or black) and then he met an old guy (who works at some office). At first the old guy didn't let him sleep there but eventually let him do what he wants in his house. I think it has the same art style as "love or hate" and "fools".

I think the mc had a crush to his friend but his friends like a senior (a girl who plays a guitar )from their gig/club. I remember that the girl already have a boyfriend
