I'm not gonna re-read this, mostly because a 15-year-old girl spends over 50 chapters of the story in love with her 23-year-old teacher (they even go out for a while). Fortunately, she ends up letting go of that infatuation and chooses to pursue a relationship with a very sweet age-appropriate boy. This is a very rare turn of events, most shoujo starts inappropriate and miserable and end the same way, so that's what makes this special.
