Old black and white manwha/manga. Can't remember much -- Main character lets a mysterious younger man (teen?) with dark hair stay with him temporarily. The young man is super nice to the main guy but is kind of mean to his friend (who's very pretty, light hair, and I think was a bar tender). The friend is suspicious of the guy but the MC is very trusting. I think it turns out the the young man knew the MC years ago and has loved him since then
