Fu Yu went to have his teeth extracted and met Gu Tong, who lived under the same roof as Fu Yu.
"I always thought you were my younger brother, how can you be older than me?"
The fat man from childhood had grown up, and Fu Yu really couldn't recognize him after such a long time.
"You are the little fat boy back then, and now you are so handsome."
"Does sister like me now?"
"I'll tell you if you act like a baby."
Concept: I always thought it was a sister-brother relationship, but Gu Tong is 1 year older than Fu Yu
