His scent was still lingering on his side of the bed and what's worst is that Kai still called the right side Kyungsoo's side, even though the boy moved out weeks ago. 

Kai's hand felt empty by his side but his heart felt heavy in his chest. It's been a month but he can't get used to not having the older's hand to hold.

While everyone laughs happily Kai laughs hallowly. There are holes in his heart, creating empty spaces and delaying his heart beats and making a slower rhythm for the boy. It seems that the young man has to learn how to get comfortable with all the new empty spaces not just in his life, but in him as well.
