Her Childhood Love

Hi, so I'm looking for a manga I've read and am sorry if it sounds very vague but I don't really remember exactly what happened.

So idk if she was isekaid or if she was just born in that world but the main char was the heroes childhood friend/love. But when he came back from his adventures he had gotten together with the princess/heroine or smth.

I think there might have been time reverse involved and the hero always came back with the other woman as his lover.

The childhood friend got fed up and got together with the evil guy, which made the hero so obsessed and convinced she had gotten brainwashed, that he attacks evil guy.


Something like this? I think? If any of you remember I would really apprechiate it.
