You were the older sister of the Kawata twins. Nahoya, the older brother, and Souya the younger brother. They're twins, also known as Smiley and Angry because of how they looks.

And you? You look like you're mixed with the two. And you're in high school, after class you'd always pick the two up to go home together. And today, they're playing on the playground while you just finished your class.

Suddenly, Nahoya tackled you down. "Hah! Nee-chan is heree!" Nahoya laughed "Nee-chan? Are you okay?" Souya asked. The two boys the looks at you.
