During the first check-up, Jong-geun discovers just how sensitive Jaeyeon’s mouth is when he lets out an unexpectedly erotic moan. Though Jong-geun tries to resist his growing attraction to Jaeyeon due to their professional relationship, Jaeyeon can’t help but flirt with him. Thus begins a secretive after-hours check-up routine between the dentist and his dangerously sensual patient.
