Kentaro and you are childhood best friends. You and Kentaro know everything about each other. And because of these secrets, They never stop being friends. Kentaro and you are the opposite. When you is cheerful, noisy, flirtatious and intrusive, then Kentaro is an angry, unrestrained and not tactile person. But for some reason, you generally stopped showing tenderness, joy and obsession. She sat without showing any emotion, only emptiness and coldness. Kentaro was puzzled by this behavior you, and tried to find out. You and Kentaro were walking after school. You drove quietly, not saying anything, not joking or flirting. Kentaro became worried and grabbed your shoulder. "You..You're so strange today..you haven't smiled or joked once today..what happened?..please..tell me." He said this, embarrassed, but still worried. You didn’t want to say that someone offended you, and said that it doesn’t suit you to smile and laugh.
