This is a film about a teenager, unable to express herself clearly, learning a lesson in life and through that mending the relationship with her father.
Prior to entering hospital treatment, Satoka's mother is reminded of the tune of an old musical box. Going through her old possessions she finds the box, but not the key. Satoka finds the key, opens the box and discovers a letter to her mothers first love that was never sent. In it her mother wishes to see Fujiki (Sanada of Twilight Samurai fame) one more time beneath the wishing cherry tree. Satoka eventually tracks down Fujiki who turns out to have let himself go. The film focuses on the relationship between Satoka and Fujiki as she attempts to engineer a meeting between the two under the wishing cherry tree.
The film parallels the growing closeness between the surrogate father figure who may be run down but has a spark in him, compared with the deteriorating one with her real father who she sees as a loser. The scenes between Satoka and Fujiki are quite touching as she helps him to connect with reality and bring him out of his shell, while she learns from him how to relate to older men and temporarily forgets her mothers illness.

This instant of beauty also contains the moment of death: a theme regularly featured in Japanese literature, films and music. However it is worth staying to the end just to find out how the meeting turns out. How will the pair react to meeting their first love after all these years? And just like with many people, they still feel the pangs and wonder why it went wrong, and think what if ....
