Hello

looking for a yaoi manga where he has a brother complex and his brother has a boyfriend which is probably is a teacher but I'm not sure if he was a teacher plus he doesnt know his brother dating with that man (probably) he just don't want to them to be alone or something like that so he always goes to their side on breaks his brother doesn't complain about it but he doesn't like either and he has a close friend that he always talks about his brother with and that guy is in love with him and one day his friend confession him at first he thinks he doesn't have feeling for him but after his friend ignores/doesn't pay attention to him like he used to do then he realizes his feelings.

I asked this last night but I still can't found it so I'm asking again.
