age appropriate? yuri isn't underage; he's an adult who can make his own decisions and give consent. there are many types of couples in this world and there was never a rule that you have to be around the same age as them. as long as an adult and minor aren't involved, it's fine.
I’m pumped that Kwon Yuri got a spin off but why tf does a teacher have to be the love interest. We need an age appropriate pair like the original :/
