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.

As the days passed, their shared life increasingly started to resemble that of a cohabiting couple. Ken would turn down drinking invitations after work, brush off his suspicious colleagues who were starting to wonder about his behavior, and head home earlier than before. By the time he arrived, Akane was already home. Wearing her school uniform with an apron over it, she was in the middle of cooking dinner. After the meal, while eating dessert, Akane gets teased by Ken: “You’re gonna get fat if you keep eating like that.” Hearing something she was already a little self-conscious about pointed out so directly, Akane starts seriously thinking about going on a diet. Ken then casually suggests, with his usual shameless grin: “How about we do sex as exercise? You burn calories and we both feel good. Best diet plan ever.” And so, that was his completely self-serving “solution” to her diet concerns.

On a holiday morning, Akane wakes up Ken, who is sprawled out and sleeping sloppily. They had made plans to go shopping together that day. Ken was exhausted from all the walking, but Akane was in high spirits because it was their first time going out together on a day off. While they were resting at the food court, they unexpectedly ran into Yui, one of Akane’s classmates. Yui misunderstood the situation, thinking Akane was doing something dangerous, and made a huge scene. She then called over Yuki, another one of Akane’s classmates. Under the relentless questioning from the two girls, Akane and Ken ended up confessing that they were living together and that they had already had sex. After finally being released by the two girls, Akane and Ken were completely drained. They decided to “rest” by going into a love hotel.
