For kaichou, what about Takagi? After all, you're sweet and kind, but we know almost nothing about you! (I swear, Takagi is one of the most mysterious of the minor characters because we know nothing of his past!)
For Cure-kun, I still stick by my opinion about you being like Eisuke.
For me, maybe Kobayashi-sensei because I want to be a teacher when I grow up and I like to help others. I'm also obsessed about mysteries. XD
