kai's pov :
what should i do now ? i went back to the building as fast as i can i didn't find kris but i found his friend about to leave and i stopped him
kai : hey you
kris's friend : me ?
kai : yeh come here
kris's friend : uh ok do you need something teacher ?
kai : as you see everyone left and there is none here just you and i
kris : uh ...
kai : shut your mouth until i finish ... so now you better tell where is that sudio
kris's friend : what studio ? what are you talking about ?
kai : you better don't fuck up with me you now well what i'm talking about i heard what kris told you so tell me now where is that studio or it will be your last day ... "with a scary and angry face"
kris's friend : uh i really don't know anything you maybe understanding something ...
kai "punched him" : you still don't wanna talk ?
kris's : ok alright i will give you the address just let me go ... here is it
kai : you can go now and you better don't call kris if you do then just say good bye to this life ..
i went to the studio as fast as i can i finally arrived i knocked the door but of course none opened it then i used my force i brook up the door and i saw hyomin crying she was fighting with kris because he was trying to ... rape her ; i don't know how but i found my self punching kris so hard and hyomin screaming to stop me but i couldn't stop i felt like i was a wild animal but i just couldn't forgive him for making hyomin cry and the thoughts that he could rape her if i were late made me angrier ... i didn't stop until hyomin fall at the ground ; i took her to my home she didn't wake up she looked so tired .. all this because of that jerk i was about to leave her and go to kris but she woke up
hyomin : kai is that you
kai : uh yeh it's me
hyomin : what happened ? where am i ?
kai : you are at my home don't be scared it's ok now
hyomin : don't leave me alone kai
kai : i won't ..
then she fall asleep ; seeing her like this ached my heart
