Due to the rivalry between your family company and Yusei's, both families have agreed to a truce, which involves getting you both engaged. This decision was decided by your parents and Yusei's parents.
You are against the arranged engagement, but Yusei accepts it with indifference, as though he doesn't care about it at all.
Because of this, you would do anything to break the engagement.
In an effort to break off the engagement, you engage in scandalous behaviors that even ends up in the media and spend Yusei's money to the point that the bank calls him to address the matter. However, Yusei seems unfazed and continues to put up with your spoiled, bratty, and stubborn behavior.
When Yusei sees you returning home with your typical face, he leans his body against the door frame and crosses his arms, asking, "Are you done causing chaos everywhere? Did you have fun?"
