Written and illustrated by manga artist, Asuka Konishi-Sensei. It created a buzz and was serialized in Pixiv, a Japanese social media service where users can post their artwork. It has been serialized in Monthly Afternoon since around 2017. In 2018, it was awarded first place for the comic category in Tsugi ni Kuru Manga Awards.

The main character, Somei Yoshino, is a daughter of the leader of Somei gumi, the largest Yakuza family group in　the western part of Japan. The story begins with Yoshino coming up to her yakuza leader/grandfather about an article she found in the tabloids. The article said that her grandfather’s yakuza group and Miyama gumi, the largest yakuza family group in the Eastern part of Japan are going to merge and cooperate.

Yoshino did not care about the main point, but another part in the article was very questionable to her. It said, “the heir and the heiress of both organizations, the grandchildren, are in a romantic relationship and they will be married very soon.” Yoshino had no idea where it came from.

Yoshino got upset and accused her grandfather. He revealed that he was the one who suggested to the leader of Miyama family to have their grandchildren engaged. He thought that his 17-year-old, only granddaughter would be sad without any boyfriend since everyone was terrified of her (family business). He also thought that the grandson of the Miyama family seemed very nice and told Yoshino to try dating him.

Eventually, grandfather persuaded Yoshino to meet with the grandson of the Miyama family. Yoshino was heading to Tokyo to greet the Miyama family. Yoshino thought it would be rude to decline the engagement without meeting the person. Also, in order to keep the relationship beetween the two families good, visiting the Miyama family was necessary. After Yoshino met with the leader of the Miyama family, she asked about his grandson, Miyama Kirishima who was supposed to be engaged to her.

Her possible fiancé, Kirishima, pretended to be a bodyguard for Yoshino while traveling and was trying to observe her whole time.

A surprised Yoshino was greeted by Kirishima as her fiance. He told her that he could not help going to see her at the station and asked her forgiveness for the silly disguise.

Yoshino felt that Kirishima was a very nice person with a good smile. As she is most likely going to decline this engagement, she felt sorry for him.

Even though he understood her intentions, he still told her that he was simply happy that she came to see him. Also, he told her it was okay to decline this engagement.

However, Yoshino felt something strange in his words.
