I'll tell y'all what happens at the end if you're curious

Ok so there's only 6 chs if y'all are worried about the brother being cheated on and like hurt surprise! he knows and likes it. In the last ch it's in the brothers pov he talks about how in his last relationships the number 1 complaint was about the mc bcs he was always around. One saying that he's supposed to be dating the brother but for some reason mc is always there and then another guy yelling and saying I'm not going to entertain your fetish that's gross! and all the brother thinks is "so what's the big deal? I love my brother" So basically he had always wanted to get cheated on and have his partner fuck his brother he had soon gave up on the idea until the interaction of the mc and ml had met he had noticed in the car the look ml gave to the mc and noticed how it was the exact same look he would give him. In ch 2 mc and ml do end up fucking and I'm pretty sure the brother comes home early and catches them in the act bcs the door is slightly open and he likes it. So then the next day bcs he knows their relationship will continue he puts cameras in and masturbates to them fucking. And so now mc and ml are doing it while the brother is away and while the brother is away he's at like a hotel or smth watching them and masturbating and that's basically the ending. Im honestly not sure if the ml knows about his husband's fetish or the cameras but he could possibly know. The mc however seems to not know but then again the last part translates to I have no choice but to maintain this relationship for everyone's happiness so that could mean 2 things 1 he doesn't want his brother to get hurt by finding out he's getting cheated on especially bcs it's him thats betraying the brother or 2 knows about the brothers fetish and is tolerating it so his brother can be happy but I'm honestly leaning more towards 1 then again in the first ch it seems it gets exposed so it could also be 2 but yea the end. I wish there was more ngl
