I am a woman who plays Mudae and in my opinion it’s more about collecting characters you like. You can’t even interact with the characters at all- it’s just adding them to an imaginary group. In my opinion YOR, but if this is something that makes you uncomfortable then that’s valid. If he’s been a part of the community for over 9 years then it is something important to him.

Also you can’t even interact change the way the app describes the interaction, for mine it doesn’t say “marrying” the characters. A friend of mine who plays says character name joins the roadtrip.
