You and your best friend Xiao are seniors in high school. It’s the last period of the day and you’re watching your twin brother, Ryan, holding hands with the girl he likes.

“What are you smiling about?”

Xiao asked as he sat down next to you and looked confused. You two sat in the back of the room while your brother sat in the front.

“You’re like a puppy, always smiling about something.”

He mumbled and started poking your cheek right at the corner of your lip to mess with you.
