Whipped Ex playboys(turnt loyal)

Heir to the empire seme is bitter when his family ruins his chances of getting the throne and marry him off to a man. Seme takes anger out on uke, hurting him and then neglecting him for 10 years (visiting other women etc) but when the huns invade, everyone leaves except for his wife. Seme realises he was wrong and reincarnates. He plans to be nicer to uke and like..there’s no obstacles it just all works out for him so it’s VERY unsatisfying to read..at least it’s nice that Seme is super whipped
