SONE-689 A baseball club member and a beautiful manager are unable to go home because of a sudden downpour, leaving them alone together in the clubroom… Kokoro Asano

Kokoro was dating a third-year boyfriend, but she secretly had feelings for Yuuki, who was on the same baseball team as her boyfriend. While working as a manager, one summer day after club activities, Kokoro was cleaning up the rooftop alone when she was suddenly caught in a torrential downpour. The door leading from the rooftop to the school building had been locked. With no choice, Kokoro went into the clubroom, only to find herself unexpectedly alone with Yuuki, who had also been left behind. With weak cell phone reception making it difficult to contact anyone outside, the two were trapped in a small space together. In the stifling summer humidity, the young man and woman grew increasingly close.
