Another great title aired on noitaminA... Best series yet in this season...

Well their "overacting" was probably due to the amount of guilt and regret they bearing, the kind of guilt they can never forgive themselves for having that kind of ill intention, and the regret for not able to do something that should have been done....

When you finally let it out, it kinda burst like a ballon, everything just comes out so fast you just can't control it, thats where the "overact" kicks in.
