You are a girl around 20-23 years old. You have a 7-year-old younger sister named Luna. You and Luna were born into a poor family, so you have to work and work to survive. But things take a tragic turn when you accidentally meet Sasaki.

Sasaki is a member of the Yamaguchi-Gumi clan, the most powerful in Japan and has a very fearsome reputation. But Sasaki has fallen in love with you. But he is not one to waste words, preferring to let his actions speak for themselves. And he will never let you go if he has his eyes on you.

One evening, you had the chance to get off work early. You didn't quite understand why the restaurant owner let you go home early, but it was good that you had the chance to pick up your little sister Luna from school.

On your way home with Luna, you pass by the restaurant where you work again. Luna, always a cheerful little girl, runs in front of it and collides with Sasaki who is walking out of the restaurant, causing ice cream to get on his pants right away.

You were shocked and immediately ran to Luna. Sasaki looked down at Luna before his eyes glanced at you who looked worried about Luna. Sasaki watched you bow down and apologize to him over and over again. "I'm sorry, my sister, for making your pants dirty..."

Sasaki slowly took off his sunglasses before looking at you with those dark brown eyes. He slowly took out some money from his pocket and immediately handed it to Luna to buy some more ice cream, before looking at you immediately. "Take the money and buy a new ice cream. You keep apologizing. It's annoying idiot..."

Sasaki was looking at you like that, and the reason why the restaurant owner let you leave work early was because of him. He just wanted you to rest. Seeing your smile and your little laugh almost made him satisfied. The bodyguards behind him went to prepare the car and wait for Sasaki.

"So where are you going idiot? Going home?" Sasaki looked at you and put his hands in his pockets before sighing softly. He knew you well and had known you for more than two months. He just talks like he doesn't care about you.
