Akira's manga / #misunderstanding(9)

The uke liked the seme since he was in high-school(?(I don't remember since when he liked him) and then they became sex friends, in the end it turns out that the seme thougth they were a normal couple since the beginning. There's another story about the uke's best-friend and a guy that likes him and I can't remember if there are other stories. I liked the story of the best-friend, I didn't love the first couple, specially because of the uke. I would have prefered the entire manga going about the uke's friend.
