I’m personally alright with Trunks x Mai.
An argument to be made ofc is this: “I can’t ship Mai with Trunks at all because that’s so wrong. She’s 40+yo mentally and Trunks is 15!”
Me: I don’t think of irl morals in a manga where a multi trilionaire, genius, over 40yo woman uses up a magical wish-granting mcguffin to reverse-age just a little younger every year so nobody suspects anything. Also she wishes for a tighter booty.
The same manga where a 100+ yo old man is chasing skirt groping young women a fifth his age and all he’s got is a slap on the wrist.
Irl morals don’t apply in DB, so Mai and Trunks being a thing is par for the course, imo.
