The only times when it feels wrong is when they're underage. Besides do you want her to go marry an 70 year old pervert that likes her body? If you really wanna feel disgusted go read or watch Moshuko Tensei that mans takes it to a whole new level of pedophilia
I already read mushoko tensei and it's fcked up like MC is a huge perv and....SPOILER
they already fcked each other (the MC and the red haired girl)
Yeah I know lmao. That's why compared to that this is nothing. Both of them are at least legal or at a decent age yk
You see it all the time in real life without the magic reincarnation stuff. Least they’re not creepy about it, like that one dude picking up grandmas in a documentary I watched years ago. Dude just had a fetish for wrinkles I swear. XD As long as they’re both of age consenting adults I don’t really mind. Not personally my cup of tea to date someone much older. But meh doesn’t bother me too much when it’s other people.
So she's like 80 or smthn in her old life and the emperor is in his 20's, what I'm Trying to say is that pene has her old memories but still has a mindset of a 20 year old cuz it be weird for an old lady dating a young guy ┐(￣ヘ￣)┌
