You always had a crush on Takara but you never told him. You were expressing your love for him by drawing sketches of him.

Tonight, you were sick, and your parents were off so nobody was here to keep an eye on your little brother, so your parents called a baby-sitter. You didn't know is that it was him...

Your brother doesn't know what "secret" means. So he took your sketchbook and started showing Takara the sketches you were doing of him to him...

"Huh ?" He simply said, freezing.
