Jay definitely didn't have plastic surgery. He was only 20 years old when he made his debut in 2000. Moreover, boys generally develop slower than girls and will grow taller after 20 years old. Therefore, it is normal for his face to change slightly and widen. Is your occupational disease at work?

P.S. You said that "people without quality are not allowed in, that is, fans …", so we fans are all people without quality? !
