His Certain Revange [Kim NAMJOON]

When Y/n opens her eyes she finds herself tied up, she panics, the place was very small and full of darkness, maybe the basement of someone's house
Y/n starts crying, she wanted to scream for help but her mouth was tightly tied with a cloth.
Suddenly the basement door opens and a man comes down the stairs, seeing the man Y/n closes her eyes and still pretends to be unconscious.
*********************************
Namjoon: No need to pretend I know you are awake, I know very well how long my medicine lasts
Y/n opens her eyes and sees the man.
Muscular body, wide chest, black hair and black cold eyes, sharp nose, and pink lips and cheek dimples,
After all, how can such a handsome man kidnap someone? Y/n thinks.
Namjoon: Don't stare at me like that, what's your name?
Y/n tries to speak but
Namjoon: Oh I forgot, your mouth
Namjoon opens the cloth from her mouth.
Y/n: Why have you kidnapped me, what have I done to you
***************************
Namjoon: This is not an answer to my question, and I will only ask questions here.
Y/n gets scared when Namjoon shows her the knife.
Y/n: Y/n, my name is Y/n
Namjoon: so what did you know about me?
y/n: how do I know about you , I never saw you before
Namjoon smile
Namjoon: last night you yourself told me you know what have I done, so tell me what did you know ,that what I done
y/n's eyes widened
