During her teenage years, Satomi Azusa was a celebrated gravure idol and an exceptionally talented baseball player. Despite her skills, she was not allowed to join her school's team due to her gender. Her father, who happened to be the team's coach, devised a plan to fulfill his daughter's dream. He enlisted Azusa's childhood friend, Hirayama Keita, to take her place on the team. Though Keita lacked any particular talent, he resembled Azusa so much that even their parents couldn't tell them apart with her dressed in a wig and girl's clothing. Keita willingly agreed to the charade and became successful, even attracting interest from professional baseball teams. However, the risk of being exposed hung over them. How long can they keep up this masquerade before they're caught? And what will be the consequences when the truth is inevitably revealed? Interestingly, the first three chapters were featured in Short Program 3.
