Season 1

Akane Misaki is a schoolgirl who has started living alone. Due to a mistake by her landlady, the same apartment was rented by her and Ken Hazama, a salaryman. The two come to an agreement that they will only live together for a week until another apartment becomes available. That same night, Akane hears that they are having sex in the apartment next door, sounds that make the teenager very horny. On the other hand, Ken realizes that Akane was masturbating and then…

Akane asks Ken as a favor to pretend to be her uncle and attend the school meeting, a request he agrees to. After the meeting ends, Ken climbs the stairs leading to the rooftop to reminisce about his old student days. Once there, Ken gropes Akane’s ass without caring if anyone sees them.

Several days have passed since Akane and Ken started living together in the same apartment. Ken is concerned about Akane because she has been coming home late lately. After picking her up from her part-time job, they both take a shower, but Akane takes measures to avoid making love.

Akane and Ken, who started living together due to a mistake by the landlady, are about to complete a week together. The landlady informs Akane that she can move to a new apartment soon. Akane reflects on returning to her normal life and feels uneasy recalling the days with Ken. On their last night together, Akane makes a bold decision.

A few weeks had passed since the cohabitation between Misaki Akane and Hasama Ken ended due to a contract mistake by the landlady. They had hardly seen each other since. Although Akane was enjoying her school life and had gotten used to living alone, she couldn’t shake off the loneliness that lingered in her heart. On the other hand, Hasama also felt an odd emptiness in his quiet apartment, often finding his thoughts drifting toward Akane. One day, Akane suddenly showed up at Hasama’s place. With a serious expression, she asked to stay in his room again. Hasama was momentarily surprised, but he easily agreed to let her move back in. Then, seeing Akane after so long, he couldn’t hold back—and leaned in for a kiss.

After Akane returned to Hasama’s room, their cohabitation began once again. However, she often came home late due to her part-time job. Worried about her, Hasama decided to pick her up from work, bringing along his dog, Gorō. On their way back, they passed by a park, where Gorō seemed eager to play, so they sat on a bench and watched him run around. As they sat there, Akane began opening up about her past. Listening attentively, Hasama advised her to rely more on the adults around her instead of carrying everything on her own. Just then, they realized Gorō was nowhere to be seen. Panicked, Akane stood up quickly to search for him but lost her balance and fell onto Hasama. He caught her in his arms… but then, his hands started moving in a rather suspicious manner.
