Yakuza Fiancé: Raise wa Tanin ga Ii

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.

After their final exams, Yoshino and Kirishima head to Yokohama to meet Yoshino's cousin, Tsubaki Akashigata, who recently moved from Kyoto. Reuniting after a long time, the three—Yoshino, Tsubaki, and Kirishima, who tagged along—explore the city together. They enjoy reminiscing and chatting about trivial things as they stroll through Yokohama. However, their fun is interrupted when Yoshino gets a call from school and has to leave, leaving the other two behind. Kirishima seizes the moment and invites Tsubaki on a casual date. Alone together, they find themselves inside the glowing Ferris wheel at night. In this private, quiet space, Kirishima turns to Tsubaki and asks her an important question.

Returning to Japan after living abroad, Nao Shioda lands a job as a TV announcer. She crosses paths with Kirishima, her ex-boyfriend from the past. In front of their friends, the two pretend to be strangers, but when they find themselves alone, Kirishima gently speaks to Nao and hands her his contact information. Meanwhile, Yoshino and Kirishima travel to Osaka. While there, Yoshino reconnects with Shoma after a long time apart. Coincidentally, Nao also arrives in Osaka to attend an event, setting the stage for their paths to cross once more.

From her seat on the bus, Nao spots Kirishima and Yoshino walking together. Unable to ignore them, she gets off at the next stop to follow. However, it's Yoshino who approaches Nao first. The two women begin to talk, and the conversation inevitably turns to their shared connection: Kirishima. Nao reveals to Yoshino some of Kirishima's past that Yoshino had no idea about. Meanwhile, Nao faces trouble of her own. Her ex-boyfriend, Ozu, has uncovered secrets about her past and her previous relationship with Kirishima, gaining leverage that could impact her future. With this power, Ozu makes a troubling demand of Nao—one that could change everything.

The semi-criminal group holding grudges against Yoshino and Kirishima, along with Azami Suou, had gathered under Ozu’s command. While Kirishima was with Nao, Yoshino spotted Ozu and his group and decided to carry out a plan on her own. Upon learning about Yoshino’s situation, Kirishima reluctantly contacted Shoma, the only person he could turn to in Osaka, to entrust Nao to him and head toward Yoshino. During this time, Kirishima called Yoshino, and the two made a significant "bet."
