not cheating, yeah the seme mentioned seeing women on and off but that was before they established a relationship.. plus we never really saw him bringing a woman home so i'd assume that since he brought the uke he stopped seeing people. the first "woman" that the uke saw was actually the semes sister so again, seme probably hasn't brought anyone home since the uke arrived + the "fluff" part is to describe the uke and semes relationship, cause despite the seme taking the uke as collateral their dynamic is pretty wholesome if you take in all the factors.
Actually I think he’s the boss of a hostess club so he’s trying 2 take care of the girls but is not romantically involved with them
literally mc gets raped like 4 times and the seme is also kind of cheating so????
