Synopsis

Based on Nitsuyama Nitsuko’s manga, the story follows Shibasaki Himari, a 27-year-old woman working at a PR agency.
Contrary to her appearance, Himari has a strong sex drive, and painful breakups caused by sexual incompatibility with past boyfriends have left her emotionally scarred.
Feeling anxious that all her friends are getting married, Himari does what she always does and invites her longtime college best friend and co-worker Hojo Kazumi out for drinks in order to vent her frustrations to him.
 
In contrast to Himari, Kazumi had had gone years without a romantic partner and showed no signs of feeling the pressure. However, when Himari confides that she wants to find someone sexually compatible, Kazumi suddenly proposes, “Want to try it out with me?”
Though shaken by the idea of crossing the line with her best friend, Himari eventually gives in, and the two take their relationship to the next level. The relationship between the pair, who had always been able to say anything to each other, begins to gradually change shape.
