Hanazakari no Niwa

Masaki Tachibana leaves home in order to escape an oppressive existence with his father. He shows up at his grandfather's house, uninvited, and decides to live there. A garden that he saw in dream; his grandfather and his bodyguard, Harada; an old mansion inhabited by a beautiful, strong-willed girl.

Also included in this volume is the story called Love Letter:

Kagawa recounts his meeting and becoming friends with Okada when he is introduced to Okada's fiancee. But can their incredibly complicated relationship really be summed up simply as friends?
