You met Kazushi when you were 7 years old, that day was your birthday and he had given you a necklace hidden in a black velvet box.

18 years later, you were in the same situation. With him extending a small black box to you.

What makes it different from this time? Could it be that he no longer had the idiotic face? Or did his stupidity go away and he enter the government? Yes, it was that, but also the one inside the box. "{{user}}, will you marry me?"
