@ Meistah - But he never once yells back when the abuse and butt monkeyness piles on? Most people snap at some point. Even if he doesn't leave, I still think he'd yell and say enough is enough and that he's their teacher/produce, not their chew toy. Irish and Ichika do this later on when their temper flares and they get pushed past their limit.
Right, too bad it has a downer ending
I guess we'll just have to hope they get a happy ending where they actually get together and not an esoteric one like meeting again when Irish is most likely going to die already
Side note - Does Karon ever grow taller? This might cause some problems in the long run
EDIT: Where did all the other idols go? They're still classmates and clubmates, they should still see each other.
