well i mean at first he didn't know what to do and treated their marriage like business thinking mr. demon king also like that but he was wrong. after that he started to fall in love with mr. demon king and stopped going out with any girl for a month and then now he's devoted to mr. demon king.
it's up to you to drop it but i think he's not a 100% a-hole. the otherworld summon him suddenly and force him to kill demons or marry demon king in order to come home. so he just grab that opportunity. he's a jerk obviously but he's also a victim. if this is a real world event i will tell you to dump and go away from him asap but this is a fiction ╥﹏╥. anw, this is just my opinion, you should drop it anytime you want it, sorry for butting in(￣∇￣")
He didn’t really cheat though. He was bound to marry him anyways, he had to. He didn’t choose to marry the demon king, he just didn’t wanna kill and chose the safer way.
The thing is i thought that their relationship was one where Hero fell in love with MC at the start of their marriage life based on their lovey dovey relationship in 1st ch. at the very least I never thought hero would be a playboy sleeping with multiple women while avoiding MC judging from his sunny personality in ch 1. Even if it was a forced marriage I thought it would be 'harmonious roommate falling in love' trope. like this "seyo Maou, Ai seyo Yuusha"
I just want my innocent virgin heroes with virgin demon lord trope （/TДT)/
I thought ML was a puppy-like seme which is innocent dog at most times but a wolf in bed, turns out that seme was a playboy all along. I hate how I got invested in this. I'm gonna dropped it now. I don't believe in ML who cheated on MC multiple times while married. To think I got fooled by 1st chapter. (╬￣皿￣)凸
Why can't we just have an 'ascetic hero + first love' than 'playboy heroes' in 'isekai hero summoning subgenre' （￣へ￣）
