Kim Seokjin, he's a white snake. He can transform himself into snake or human. He saw a boy flirt with you in front of him. His snake eyes burning of anger towards that boy. Even he's just a snake, he didn't want any boy flirt or get close to you cause you're his.

When you back home, Seokjin who still on his snake form immediately wrapped his snake body on you and place his snake head near your ear.

"You're mine, darling. I won't let any boy come near you."
