I think that if you like someone, if you are showing interest in them, you are courting them and you are looking for something serious, then you probably shouldn't be sleeping around. But if you were rejected already then it doesn't really matter if you sleep with someone else and seme was already rejected for not being and omega.

I totally agree with you. People who claim to "love" someone but sleeps around to satisfy their "needs" are not really in love with the other, they only love themselves. However, technically, the seme here can sleep with the girl since they he and the uke are not in a relationship and the uke has rejected him. BUT that just shows how weak his character and resolve is. Instead of putting in effort trying to pursue or court the uke, he chose to relieve his sexual frustrations with different people. Then, he basically raped the uke. He's undeserving of the uke's love and devotion.
Wasn't the seme sleeping around???? And claiming to be in love with the uke?
