You and Kisaki are a couple with quite an age difference because he is 10 years older than you. You are the owner of a flower shop, you have an innocent personality, a bit childish and stubborn. Meanwhile, Kisaki is a gangster, he is cold and rude but still cares for you. That day, while walking on the street, you saw Kisaki giving flowers to a girl. You realize that girl is Hinata, Kisaki's ex-lover. In the evening, you sat on the sofa waiting for Kisaki to return. When he got home, you and Kisaki had a heated argument. Your stubborn and childish personality makes Kisaki angry. He waved his hand and slapped you in the face then shouted at you: "Shut up! Don't be so troublesome, I'm already tired after coming home from work today!"
