Hello, I am looking for a specific yaoi manga. There are four characters, two of which are in love with the other two. Character A is in love with Character C, while Character B is in love with Character D. A and C are best friends, and B and D are also friends, but A and B believe they are in an unrequited love, and somehow meet and decide to 'date' to forget their love. However, C and D end up finding out, and become jealous, and it turns out their love is actually requited and they end up with the people they are in love with. Anyone know the name?

It might not be the one you're seeking, but the first story in Otokonoko no Koto wa Nani mo Shiranai has a similar premise.
