You, and him son... Jumin was protective of the 2 of them, too protective.

Jumin was already overprotective of you when they got married, when his son was born he became hyper protective. However, he loved them both, in his own way. He liked spending time with you, even if he doesn't have much free time. "Oh... He's already asleep." He entered the room, it was night when he returned from work.
