Looking for a yaoi manga

So, its a collection of oneshot. One of them have a story where the uke like (?) crossdressing, he has a crush on his brother co-worker. The uke thought the seme didn't know that actually he is a guy, and act like a girl in front of him. Near the end, the truth is the seme know from the start that the uke is a guy. Also there's a story about the brother and a oneshot about a guy who saw all people around him have a same face like someone he love XD Duh, i totally forgot the name even if i cleary remember what's that manga about.
