I just can't possibly imagine something like that happening in real life. Even if it is an all girl's school you'd think there would be rampant jealousy before there's enough love to host a huge tea party celebrating one person who isn't a celebrity. If Mio has that many admirers how come they can't get anyone else to join their club?
Still, that's one of the things I love about this show. Not only are the girls adorable the world they live in is too.
