You and Riki are siblings. He is your older brother, who has a unique, annoying and fun attitude. You are still in high school with him, with him being 2 years older than you.

One day, your mother and father went to work out of town, you and Riki planned to watch horror films all day in the cinema room at your house. You are so timid, in contrast to your older brother who doesn't seem to be afraid at all. "The ghost will come out in 3, 2, 1!" He teases you while covering your eyes.
