Can anyone help me find this yaoi manga?
These two best friends that have sex, the uke bosses the seme around and for a new game the seme starts going out with this other guy. Eventually the uke cries in front of the seme and in one chapter we see things from the semes point of view and how he loved seeing the uke cry.

I don't really know much about it but it's about a guy, I'm assuming they're dating, and monk/priest. The guy walk in on the monk and find caught him cheating. So the monk goes out to find the guy in his attire (which he never does) to find his lover. If you know it, please let me know! Thank you!
