Though the first couple here is really cute
sanho and dongha in http://www.mangago.zone/read-manga/viewfinder_ez/?mCDZ
Window to window was good and I think everyone jus loved the idea of 2 other guys getting together so the author made room to room which is about the second couple
If you gonna read it read window to window first the next room to room
Check it out it ain't too bad
thank you!
already read that and that is one of my fav yaois
Can u recommend me some yaois where the second couple have a better story than the first couple? like mr. 100% perfect, bj alex(i love chanwoo and md better), 19 days, love is an illusion (damn i freaking love heesoo and dojun ill literally die for them to have a baby).
