Too Easy!

It's a puzzle box joke, it brings back memories of first encounter experiences.

Okay... Naoya will know to never ask Misako for a favor ever again.
Frustration and laziness can lead to very interesting things. Let's hope Misako can avoid getting in trouble with Max for destroying his puzzle box which was entrusted to Naoya.

I would totally cry if someone did that to my puzzle box. I made a road trip all the way to Hakone just to buy one and they're so cool. It's easy to open if you understand the mechanism. If you don't know, then you'll be spending an irritating 30 minutes on it (if your attention lasts that long).
