It sounds exactly like a comic on Tapastic called Valentine https://tapas.io/series/valentine_comics_eng
The part you're talking about is a really recent update, though

OMG YESSSSS!!! Thank you so much
So, there is this yaoi about these two guys, one gay and one not. The scene that I really remember from it is where the gay one needs the spend the night at the not gay ones apartment and he has a really cute moment over stealing his pillow. Then he wakes up on the not gay ones chest, in the morning sunlight wishing that he was his. He then steals a kiss. DOES ANYBODY KNOW WHAT I AM TALKING ABOUT????
