What I like about PT is that Fuuko is realistic and it's easy to feel sympathy for her.
She does a brilliant job of showing how you can mature and grow from each crush that you have.
Plus, I found it very difficult to side with either male counter-part. When you think that the energetic and fun-loving Daiya is the one, quiet, arrogant Ichi shows his softer side and sweeps you off your feet.

Sigh, you'll find yourself in the love triangle in no time.
