For me what I don’t like about it is that he mainly sees her as the girl from back then. I can’t remember her name. The one that shows up in the MCs dream. I don’t know if he is still like this but from what I can see he stays with her mainly because of the fact that she is the recarnation of the other girl. And honestly redy suits her a lot better. And even if she does have the mind of an older person her body is still of a kids so I hope they don’t do anything until she gets older. I get that love is love but for now she is off limits since she is still growing and developing and he is a full grown adult and older and if I have to be honest they don’t really go well together.
Im confused at the people who think its wrong for Ren to like Irene solely based off the age issue (him liking her cause shes a reincarnation is a separate issue). Age in this story is hella off and she has memories of living 20+ years before. She's not a minor??
