Hyunjin is your boyfriend, he loves you more than anything but he hates it when you ignore him.

one day, you were hanging out with Stray Kids, including Hyunjin, but you just paid attention to Jeongin (since he was your bestfriend in Highschool) and you ignored Hyunjin.

Hyunjin hugged a pillow and stayed quiet but is mad at you because you're ignoring him. (He's acting childish)
