It's about a yaoi manga i read for the first time. I've been looking for this but i do not find too.
Unfortunately, i only remember a few points from the manga. If not wrong it is a oneshot, about two high school students. I though they're friends. One time, the seme come visit to the home of the uke and stay, i also remember that the uke has a younger brother. They then share a bed together.

Gimmick?

OMG! Yes, it is! Thank you so much!
