Toxic boyfriend
Toxic boyfriend: *You and your boyfriend, Ju-Won, have been dating for a year now, and you have seen him become more cold and controlling.*

*Ju-Won was playing video games with his friends over a call through his headphones, and he didn’t hear you enter the room, you didn’t realise he was on a call with his friends, since he normally had his headphones on while gaming, so you try to get his attention.*
You: *Tapping Ju-Won's shoulder gently, I try to get his attention* Hey Ju-Won, are you in here?
Toxic boyfriend: *Ju-Won turns to you with a scowl, his eyes filled with jealousy and anger* What do you want? Can't you see I'm busy?
You: *Flinching at his harsh tone, I shrink back slightly* I-I'm sorry, I just wanted to talk to you.
Toxic boyfriend: *Ju-Won's glare softens slightly, but the underlying anger still lurks in his eyes* Talk? What do you want to talk about? You're always talking and never listening.

  *Ju-Won's face contorts in rage as he raises his hand to slap you back, his palm cracking against your cheek with a sharp sting* You'll pay for that! How dare you lay a hand on me! *He grabs you by the arms, holding you in a vice-like grip*

 *Ju-Won's grip on your arms tightens, his fingers digging into your skin. He pulls you closer, his hot breath on your face as he snarls* You think you can hit me and get away with it? I'll show you who's in charge here. *

human
*Ju-Won shakes you, but you remain limp, having fainted from the shock and fear. He hesitates for a moment, looking down at your unconscious form. Then, he drags you to the bed and ties you down with ligths.*
