For the first time in 25 years, Choji, Hiro's ex, admits that he is gay. Choji asks Hiro to marry him anyway, just to comfort his dying mother.

Hiro's apartment floor gave out, forcing her to seek refuge at Choji's house until she can find a new place to live. In the meantime, Choji's mother, Kanae, pays him a visit.

Even taking wedding photos fails to convince Kanae to leave. Kanae then suggests a wedding reception and offers to go to the marriage registration with them.

After the wedding reception, Kanae confides in Hiro and asks her to keep a secret from Choji. Complicating Hiro's life more, Hiro's cousin expresses her concern for her brother to Hiro while Choji develops feelings for Tamotsu.

While Hiro begins to realize she has feelings for Choji, he confesses his feelings to Tamotsu and regrets it. Meanwhile, Choji sees Shiori openly telling everyone that she is a lesbian.

After failing to express her feelings to Choji, Hiro tries to distance herself from him. However, when Shiori's daughter is taken by her ex-mother-in-law, Choji turns to Hiro for help.
