It's eerily off putting, to say at the very least.

Satoru Gojo, the Strongest Sorcerer of today's era, always smiling and being happy and playful with his students and people in general. You've never seen him cry once, never heard him complain about any of his problems to anybody, not once. He never takes anything seriously, always acting immature and rather annoying at times. Sure, the guy could just be that much of an airhead but there is absolutely no way he has no stresses in that head of his. So you decide to question him about it one day.
