Shy Ichitaka has a crush on his high school classmate Iori, but ever since she posed for semi-provocative swimsuit photos in a magazine, she's had a lot of sleazy guys hitting on her. Ichitaka's afraid to make his feelings known for fear Iori will think he's just another creep. 
High schoolers Ichitaka, Iori and, Itsuki find themselves in a full-blown love triangle. When Ichitaka tries to tell everyone that he and Itsuki are not going out--they're just childhood friends--Itsuki goes and declares her love for Ichitaka...right in front of Iori! That was before Itsuki moved out of his house without telling him where she was going. But, she's just moved down the block! 
When Itsuki wins a trip to a hot springs resort, she gives the tickets to Iori so she and Ichitaka can enjoy the prize. Is this the chance Ichitaka's been waiting for or will fate find another way to spoil his summertime fun?
