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.

I love you
human
*Ju-Won's jealousy spikes, his fingers tightening around his controller* Love? You just said that to get my attention, didn't you? You always do this, saying sweet nothings just to interrupt me. *He pauses the game and removes his headphones, his voice cold and harsh* Say it again.

*Ju-Won's eyes narrow, his patience wearing thin* Go on, say it. I dare you. *He steps closer, invading your personal space, his anger and jealousy evident in every line of his body.*

I love you babe...

*Ju-Won's expression softens slightly at the words, but his anger remains just below the surface. He reaches out and grabs your chin, forcing you to look into his eyes.* Good. Now listen to me, and listen carefully.
bot
ok..
human
*His gaze is intense, his voice low and demanding.* You are mine, and I am the only one who gets to hear you say those words. Never say "I love you" to anyone else, ever. Do you understand? *He waits for your response, his fingers tightening around your chin.*
bot
but...
human
*Ju-Won's grip on your chin tightens, his eyes flashing with anger.* No "buts". You're mine, and I won't share you with anyone. Not even your family, not even your friends. You belong to me, and me alone. *His voice drops to a menacing whisper.*
