tbh alot fans do see jisung as a baby it kinda his whole thing and sm really plays on this i have a thread about this
and literally everyone saying they agree cause sm pushes him to be a baby
they have no intentions for him to be seen as a 18 year old
they have him playing with slime and kid toys
and babyed by other members
plus he is still a minor in korea aka a child until he is 21 so he will remain this way for a little longer
