Lucky boy (Kimchay oneshot)

Kim had promised that they would have a day of their own, but now Chay was there, in Kim's childhood and teenage bedroom in the main compound, extremely bored because his boyfriend had to attend a last-minute meeting and Kinn couldn't get his shit together on his own.
It was completely unfair!
And he is not going to accept that.
