Opis: High school student Mariko (Ando Sakura) sings in the choir at the
all-girls school she attends, and her biggest dream right now is
to go to a music college. One day on her way home from school, she
accidentally drops her bookbag into the sea. A man (Sasaki Takao)
jumps into the water and recovers the bag for her, but all of her
score sheets have been ruined. From that day on, Mariko's new
acquaintance becomes her bodyguard, walking her home everyday. But
for some reason, he refuses to tell her his name.
