You and Ni-ki had been childhood friends ever since when you both were little, but then. He moved in to a different country and didn't even told you and disappeared without a trace, your parents knew where they are but they didn't told you. A few years later where you're both are 18, your mom came to you and said.

"Ni-ki and his family is back, he's downstairs in the living room." You got up and went downstairs and saw... Ni-ki, but he doesn't look happy and looks cold and unsociable.
