hyomin's pov :
i woke up and i found my self in another bed another room i couldn't remember anything ! why am i here ? where am i ? what happened ? i kept asking my self then i remembered when i was dancing with kris then he tried to .. omg i can't remember what happened after ! is this kris's room uh omg please no ! and i started crying then the door opened i was afraid because i thought it was kris but no it was kai the one i miss so much the one i love so much ...
kai : why are you crying ? are you ok ?
hyomin : what happened yesterday ? why am i here ? did kris ...
kai : no nothing happened everything is ok you are safe here :)
after seeing his bright smile i felt so happy and safe and after a while i remembered the rest ... kai saved me again !
hyomin : thank you
kai : for what ?
hyomin : for saving my life again ; i really don't know what to say .. thanking you is the least thing i can do ..
kai : don't say anything and let me hug you
then he hugged me i was chocked i didn't know what to do then he said "i miss you" i couldn't help but to cry
kai : why are you crying again ?
hyomin : because i miss you
kai : sorry for making you cry sorry for hurting you ..
hyomin : you don't need to say sorry you are with me now and it's really enough for me i won't think about the past and you have to do the same thing ..
kai : but ..
hyomin : there is no but
kai : i have to tell you something
hyomin : no please not now i only want to stay with you and look at your face ...
he had something important to say he had to explain many things but i wasn't ready to hear anything the only thing i want is staying with him ... maybe i should be thankful to kris ! because of him i'm with kai now
kai : do you want to eat something ?
hyomin : uh yeah please
kai : ok wait here i'll go buy something
hyomin : ok ..
i was looking at his room it was clean ; beautiful .. i liked it then i found something strange it was a diary ; kai's diary ! i opened it in a random page and i read some lines "i don't want my fate to be like my mother i have to do something i can't be with her even if i love her" i couldn't finish reading because i heard the door opened ..
kai : i'm back
hyomin : welcome back :)
what did he mean ? he doesn't want his fate to be like his mom ? what happened to his mom ? is it me the girl who can't be with her ?
hyomin : kai ! you have never talked about your parents i don't know anything about them ! are they still alive
kai : what ! uh why all of a sudden ! why did you ask about them ? "with a poker face"
hyomin : uh nothing i just wanna know more about you !
kai : uh ok as you said let's not talk about anything now .. let's just think about us now .
"i wonder what is he hidding !"
