Title: Your Love Belongs to Me
Mochizuki and Ishio have a lot in common. They are both captains of their respective martial arts teams, have secondary sexes, and hate each other. Mochizuki is an omega, and Ishio is an alpha, but they aren't drawn to each other. The only reason they interact at all is that they are forced to share a dojo, which results in numerous skirmishes between the teams. To assert their dominance, the two captains spend much of their time trying to embarrass or fight each other, with little to no success.

It is then that Mochizuki notices how shy and nervous Ishio gets around him when it comes to anything remotely sexual or affectionate.
