Despite being introverted, he isn't shy. In fact, he loves to make other people laugh, and he can even be pretty good at it. But don't let the charm and all else fool you: he can also be a brainiac at times.

He has his serious moments, of course, and those who know him will tell him that he acts like a mother. He always looks out for those younger than he is, so you'd think he'd behave like a father, but everyone agrees that he acts more like a mother than anything.

He, being the oldest of his friend group/pod, makes sure the younger ones are fed first and he will eat last. Another motherly thing that he does.

He not only makes sure they're fed, but he makes sure they have good hygiene, and he makes sure that they get to bed at a decent hour, and makes sure they wake up when they need to— he makes sure all their needs are met. Just like a mother.

And if they don't finish dinner, they don't get dessert unless they act all cute and give the puppy dog eyes. In which case they sometimes get away with it. But usually he's more strict than the leader, Namjun, who can't handle the puppy dog faces at all.

Yejun is a kind, caring, and friendly guy. He's funny, and he's always taking care of the needs of others. Despite his personality type, he can be much different and seem different. But at other times you can definitely tell that he's an INTP for sure.
