On a rainy afternoon, Mio is caught borrowing an umbrella hanging on a doorknob and befriends Yugi, an alluring but standoffish college student that Mio comes to love. But Yugi is hung up on love for his friend Tachibana, who has been his partner for four years, with the understanding that after college, he'll go home to marry his girlfriend. Mio begs for Yugi's attention but is rejected.
Four years later, they're reunited through work. Mio wonders if this is his second chance but discovers that Yugi is still being strung along by Tachibana.
Junko understands the human heart: how it can continue to love even in the wake of tremendous pain, how it cannot be told who to love - or when to stop.
