*Hyerin?* Kai's eyes widened at Hyerin sleeping on the bed, but, in... boys clothing?    Wait! And are those clothings the same one that Sungjae wore this morning?   Kai was puzzled, really puzzled. *This is a scooby-doo moment..* He thought and went over to Hyerin to take a closer look if he didn't mistook seeing Sungjae as Hyerin.   Kai peered at her and gasped, it was Hyerin! He saw the wig on the other side of the bed and saw a phone in Hyerin's hands.   Very slowly, Kai reached out and slowly took the phone away from her, making sure not to wake her up.

Ugh!" She rolled her eyes in disgust.   "Wet boy?" Kai asked,"Yep! He was dripping wet and was wearing a white t-shirt! You didn't come and save me, oppa! I hate you!" Jisun pouted and hit him.   *Dripping wet? Sungju w
