Katsumi, a daughter of the famous yakuza in Japan, has always imagined herself taking over the family company alongside her twin brother, Kento. She was not in good mental health after all that had happened to her in the past, so she was not looking forward to it. One night, their parents returned from a business trip in Seoul, where they had determined that the twins should begin living the lives they desired outside of Japan.
Their trip to a different country would teach them a lot of new things. She had to live under a different name to conceal her family history. With the help of family members who resided in Seoul, she met five great friends, and she became increasingly attached to them the longer she stayed. Although not everything was roses and sunshine, there were a slew of issues along the way. Despite this, the friendship between the group of friends became stronger with each difficulty they solved. Surprisingly sparking the start of a relationship.
Even if her dreams are gradually becoming reality, her deadly history has not abandoned her. As a result, she now has two options: she can either give up the desired life or continue to strive for it.
