Can someone help me find this manga about two male teachers in an all boys school. Uke-kun was originally a trainee under seme-kun Seme-kun WAS the straight, rationale senpai.
Uke-kun would wear a jersey. Some of their students (also a couple) would often ask them for advise. It's a fluffy manga. Cute and light, no angst or drama. Please help me find it.
