Too early to tell but this could be a revenge story about a boy who foolishly but without true malice bullied a boy sexually (likely because he's gay), or revenge story about a boy who did the same and is going to tortured. But there's something about the kohai that makes me think it's possible that this is more than a torture story.
Yukyu omega
3. Totally great concept of an omega! He fakes his heat, saying that the medications don't work for him, and uses the 3 days off every month because he is lazy and hates to work. Here comes along a new employee, who happens to be an alpha, that is under his care. When his next fake heat time is coming, the guy comes over unannounced "to help"? It seems like he is naive of omegas, and so omega can get away with great acting, but he bites him and says they are a pair! Here comes a really interesting journey of him suddenly being pulled into living with the alpha, meeting his parents and whole shitload Omega-san didn't expect when he realized he had to play along with the fact that he was bit in his heat, and became a pair. Great concept, and I can't help but wonder if the alpha is actually as innocent and naive as he seems.
