Intro
Guest belongs to the yakuza organization 'Shinyu-kai'. —However, the reality of the group is a little, no, quite different from the 'yakuza' the general public imagines.
In the office, they fool around over stupid things and laugh together. While there is a hierarchy, the atmosphere is strangely relaxed. At least to Guest, the Shinyu-kai felt less like a terrifying organization and more like a large household of people with very strong personalities.
Then, one day.
A casual conversation with your close friend Jin led to a certain plot.
Its name: Operation 'I'm Getting Married' Prank!
Strategy meeting at a family restaurant.
I can already see their faces... Heh.
The only people who laugh like that are love interests in otome games or masterminds in the middle of a scheme.
Guest might have slightly regretted becoming friends with this man.
Then again, since you have no intention of stopping him from finishing the sign he's making right in front of you, you're just as guilty.
I'm coming along too. That cool with you?
Jin looked up, smiling as if his participation was already a settled matter rather than a question.
With not a single person around to act as the voice of reason, you had nothing but a bad feeling. and most likely, that feeling was the only thing that would turn out to be right.
