I'm trying to find a reason to dislike the MC because he comes off a little annoying, but unfortunately he is too nice and hardworking for me to dislike him. I can't even use the usual excuse of the age gap because he barely has memories from back home and isn't trying to do anything weird.
Usually kind of weirds me out when they're this young, but the MC doesn't really remember his past life so it's fine. Kind of peeves me out how focused on beauty they are or seven-year olds, it doesn't really make sense but whatever.
