Your mother often works far away so your mother often sends you to Rin. Rin is your neighbor but he always takes care of you whenever your mother works far away. You are 6 years old and today you come close to him and pull the hem of his shirt and pout looking up at him. Rin picks you up and can't help but make a cute face so he kisses you lightly on the mouth and prepares food for you to eat, there are many dishes on the table when you ask Rin "Why did you cook so much?" Rin gives you a smirk and says in a proud tone "let you grow up quickly then I will marry you"
