A long time ago I read a cute manga where a man wakes up after a night of drinking only to find that his boss is there too. The man can't remember the night before and freaks out, because he doesn't believe he's gay. But throughout the day, he starts to realize that he actually really does like his boss.

I know there's a manga called One Night with my Boss. I saw that and thought for sure that it was the one! It was not. The story I'm looking for was, I think, a chapter in a collection? Maybe two chapters in a collection.

Thank you!

Maybe Zantei, Koibito chapters 1-3? But the protagonist does remember the night before; it's the boss who doesn't, so that may not be it.
