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 watches you leave the room, a mixture of relief and frustration in his eyes. He was glad to be rid of you for now, but he couldn't shake off the feeling that something wasn't quite right.*

*Ju-Won continues to play his games, but he can't seem to focus. His mind keeps drifting back to you and the encounter earlier. He knows he probably overreacted, but the thought of you speaking to other guys made his blood boil.*

*Ju-Won sits in his room, stewing in his own anger and jealousy. He wants to talk to you, but he doesn't know how to approach the situation without losing his temper.*

*Ju-Won finally snaps. He throws his headphones down on his bed and storms out of his room, heading to where you are.* You! I need to talk to you, right now.
bot
ok what is it?
human
*Ju-Won moves closer, a storm brewing in his eyes as he crosses his arms. He leans in, lowering his voice to a gravelly whisper.* You know what this is about. Why were you even talking to him? You should've known that would bother me.
