The ronin student Yoshikawa was in a tight spot. He always greeted his crush, Mrs. Aina, in the apartment hallway. He accidentally opened a package addressed to her, which turned out to be his downfall. To alleviate her nightly troubles, Aina bought a front-hook bra and asked Yoshikawa for his opinion on it. 'No peeking while I change,' she said. All Yoshikawa could do was stare in disbelief. Coming to his senses, he hurried after Aina but ended up seeing her change due to circumstances beyond his control.
