Everything's blurry

-Who are you-

I'm Park Jinhoo, i think I've gotten kidnapped. I woke up in this room, there's pictures of people on the walls and it had a bed and some dressers. My head really hurt and I couldn't remember much before any of this. I looked around to see if there was a way to escape or at least get help, I suddenly saw a phone on a night stand and grabbed it to see if I could call for help.

Text message-

Random-
hey
I see you've found your phone
here's the rules
I'm only going to say it once
you break them then you will be punished
You have 3 simple rules
1. do not try to escape, it's impossible
2. listen to me at all times
3. don't call for help, it's hopeless
oh and btw everyone thinks your dead, so nobody is looking for you.

Jinhoo-
Who are you

Random-
C'mon Jinhoo, you know me.
Think I know you can figure it out.

I tried so hard to think, and then this name popped up in my mind. I didn't know who this person was, but I had a big feeling it is this person.

Jinhoo-
Are you
Bang Chan

Bang Chan-
Ding!
Correct!
I knew you'd get it, good girl.
now I'm running errands right now but soon I will be back to see you.

Jinhoo-
Where am I?
Tell me

Bang Chan-
Now sweetie, I can't do that ;)
Sorry.

Jinhoo-
Asshole
Fine, how long have I been here?

Bang Chan-
Not too long, just 3 days
I drugged you so you would be knocked out for awhile, I also erased some things from your mind ;)

Jinhoo-
What the hell.

Bang Chan-
now go to bed, by the time I get there you better be asleep.

Jinhoo-
No I want
Out of here.

Bang Chan-
I said go to bed! I mean it.
I will hurt you if you don't listen
I told you the rules now listen and go to bed.

I decided to listen because he told me to listen to him or I'll get hurt. I can remember a little, Bang Chan is strong and a little intimidating. Everything else is still a blur though, I just can't remember much.
Everything's blurry to me, I need to figure out what happened to me.
