I'm looking for a BL manga that I read a while ago but have forgotten the title of. Hopefully, I can remember enough for someone to know the title.

What I remember is:

• one character (the uke?) is drunk and mistakes his neighbour's apartment for his
• somewhere alone the line, they end up sleeping together
  -the uke tries to act tough and break up with the other but ultimately fails

I hope that's enough detail for someone to know what manga I'm talking about but it was so long ago that I read this that my memory is a little vague on this.

Sounds a bit like Sweet heart trigger although it was the seme who was drunk and entered the uke’s room.
Edit: remembered Umeya-kun no Haru also had a drunk scene...and they were neighbours.
