Aoi Takigami is feeling down after his best friend, who Aoi has been in love with since they were in high school, gets married. Unable to endure the glamorous reception, he leaves, and large raindrops begin to fall from the sky, as if reflecting his feelings. Thinking it's okay to have a little drink on days like this, Aoi heads into a bar that catches his eye. There he meets Kengo, a bartender with kind eyes. As expected, the brokenhearted Aoi drinks until he's sick, and Kengo looks after him. Kengo takes Aoi home but is unable to forget his tearful expression... The next morning, Aoi wakes up and remembers his rude behavior, and returns to Kengo's bar to apologize. That's when their story begins...
