Yakuza Fiancé: Raise wa Tanin ga Ii (Original Japanese Version)

Yoshino, the granddaughter of the local yakuza boss in Osaka, is shocked when she learns that to establish peace between their gangs, she is supposed to become engaged to the grandson of a boss from Tokyo.

The daughter of the president of another subsidiary of the Tokusa group has gone missing, so Yoshino must be accompanied around the clock by Kirishima for her safety.

As she and Kirishima try to figure each other out, some visitors from Kansai cast an ominious light on Yoshino's stay in Tokyo.

After a tense encounter between Kirishima and Shouma, Shouma drives back to Osaka. Yoshino gets the sense that something is spoiling Kirishima's mood and confronts him. Like every year, Yoshino catches a summer flu.

Yoshino's cousin Tsubaki is moving from Kyoto to Yokohama, which leads to a three-person outing with the two of them and Kirishima.

Yoshino and Kirishima travel to Osaka. She wonders if he is just attached to her or maybe even likes her. But at the same time, Kirishima's former love interest, Nao, is also staying there.

Yoshino meets Nao at the university, and they exchange contact information. However, Nao is being blackmailed by Ozu to send Kirishima and Yoshino to a place where he can eliminate both of them.

Being blackmailed by Ozu, Nao attempts to trap Kirishima so that the thugs he recently viciously beat up to the point of hospitalization can take revenge on him. Yoshino uncovers the entire scheme and approaches Ozu on her own initiative.

While Kirishima is dealing with the men on his tail and meets a certain individual, Yoshino must handle things alone with Naoya.

After settling the matter with Ozu and reflecting on a couple of things with Shouma, Yoshino and Kirishima have a chat. What is the status of their bet?

Despite resolving the matter with Ozu, Yoshino has additional problems to confront: Kirishima and Shouma.
