It also explores the main duo's relationships with several side characters, such as Haruka Kiyan, a member of the school's track team who feels hurt by Akira's cold, avoidant behavior; and Chihiro Kujou, Kondo's old college buddy and writing partner who has became a successful author in the years since they grew apart.
The manga is notable for how tastefully it handles a subject which could easily come off as creepy or exploitative. It won the 63rd Shogakukan Manga Award in 2018, the year in which it also received an anime adaptation that is available for streaming on Amazon Prime.
- Age-Gap Romance: Akira expressed a romantic attraction toward Kondo, who is over twice her age.
- Amicable Exes: Kondo mentioned that he and his former wife chat about their son Yuuto over the phone.
- Because You Were Nice to Me: While despairing over her injury, Akira tucked into a restaurant named Garden to avoid the rain. Kondo gave her some coffee and showed her one of his party tricks, starting her fascination with him.
- Bittersweet Ending: The manga ends with Kondo finally rejecting Akira outright when she visits his apartment on New Year's day, after which Akira stops working at Garden. Both have obviously grown stronger from the experience, with Akira entering rehabilitation and Kondo working on a new novel, but they never meet again.

- Burger Fool: Garden doesn't sell fast food, but it's very casual and not a prestigious place to work.
- Compensated Dating: Discussed; Kondo puts off Akira's advances by saying that people will assume that he's paying for her company if they date. She doesn't care.
- Could Have Been A Contender: Kondo worked on novels for years, and whether or not he was right to move on is an ongoing question in his life. Akira is developing a similar attitude towards running.
- Intergenerational Friendship: Kondo insists that he sees his relationship with the much younger Akira as a non-romantic friendship. She isn't thrilled about the "non-romantic" part.
