My Little Lover

High-school seniors Chiyomi and Shunichi were once childhood sweethearts, but have since drifted apart and have not spoken for years. Chiyomi is initially pleased when her friend, Riku, confesses his feelings for her, but her joy is soon tempered by a chance sighting of Shunichi acting intimately with classmate Sayori. Suddenly, Chiyomi realizes that she has never completely gotten over Shunichi.

Caught in a rainstorm, Chiyomi reminisces about how much happier she was when she was a child and expresses a wish "to be little again." Unfortunately, she is shrunk down to 15 centimeters! The next day, Shunichi discovers her in a park and starts pinching himself in disbelief! Although her disappearance causes her family to fret, Chiyomi begs a bewildered Shunichi to harbor her in his room.

Chiyomi decides to lie to her parents and say that she is attending a dance workshop in Tokyo.In the meantime, Shunichi sneaks Chiyomi into a local shrine that is home to a sacred mallet. According to a legend that Shunichi's grandmother once told him, a thumb-sized princess attained human height with the help of this mallet. Shunichi hopes the mallet will save Chiyomi, but ends up disappointed.

Shunichi initially rejects a plea from his friend Sho to rejoin the kendo team for an important match, but changes his mind after being encouraged by Chiyomi and his mother, Emiko. Although his team enters the match as underdogs, Shunichi puts up a good fight. In the end, however, he is defeated. As he wallows in self-pity behind the gym, Chiyomi finds herself unable to find words to comfort him.

Dissatisfied with Shunichi's efforts to make clothes from a handkerchief, Chiyomi decides to head home and sneak out some outfits she used to dress her dolls with. After pulling this off, she returns to Shunichi's home-and is startled to find a mysterious couple there! Believing them to be burglars, she tries to drive them away, and eventually succeeds by playing a CD at deafening volume.

As Chiyomi hides in the chest pocket of Shunichi's uniform, her eyes meet Takagi's, and she quickly hides herself. On the other hand, Sayori is shocked to learn that her father, a hospital director, has remarried without her knowledge. Seeing this, Emiko takes Sayori to her home, and she spends the night there. That night, Sayori comes into Shunichi's room and tries to kiss him.
