6. Darling 2002
Nishihara is odd-ball president of the puppet club, (yes, that's right, puppet club) and desperate to keep it from being shut down. What he needs is a new member but grabbing the person next to you isn't a good idea when you're standing by Moriya Koyo, the scariest guy in school. Moriya tells Nishihara off, but entranced by his beautiful voice, Nishihara becomes determined to win Moriya over to the puppet club! Stalking, badgering, and chasing, nothing is off limits for Nishihara.
