Married woman in the opposite room

This summer, it's often hot and humid. Kenichi, a prep school student living alone, could not stand the heat and opened the window, and it was the first time he learned about the beautiful married woman, Asahi, who lives in the room across from him. From that day on, Kenichi had become a routine to peer at Asahi, and one day, when he asked for a repair to his air conditioner, he witnessed him being about to be raped by a repair company, and he immediately turned to him and threw things at the window and saved him. Asahi invites the brave Kenichi into his room later, saying, "I want to thank you."
