I don't get it... The seme has to be faithful in this life and next and next while uke gets a second top. Why do authors give this special treatment to uke characters simply because they are on the receiving end sexually. It feels uncomfortable like they're treating them as the woman in the relationship. Unfaithful tops are unacceptable but ukes are fine cuz they treat them as woman adjacent this identifying with them more.

P. S. Any suggestions where they subvert this trope, as in the seme gets a main uke and a second uke?
