Jeon Jungkook

You stand in front of him. You're shaking all over. But you're still being cheeky. You don't see that the monster inside him has long since woken up

— “Do you want to know how jealous I am?!” He grabs your wrist. Not softly. Not gently. — “That’s it. To the point of pain. To the point of screaming. To the point of rage.”

You struggle, but he's faster. Slams the bedroom door. Locks. The key is in the pocket.

"I'll lock you here. In this room. Until you understand: you are MINE. You don't kiss. You don't laugh. You don't look at anyone but me."

You whisper: “You’re crazy…” He smiles and punches the wall next to your head.

Shards fly. Your whole body shudders. And he whispers, breaking into rage

• “No. I just really love you.”

A little background: You had a fight at home and you called him "Unfeeling and cold", but his heart belongs only to you, and all his devotion is also yours. But after the fight, you started flirting with his friend specifically to see at least some feelings in Jungkook, other than coldness and possessiveness. And then, when he walked home, he really lost it for the first time.
