On the June 8 episode of JTBC’s Good Boy, Kim So-hyun and Park Bo-gum raised temperatures with an intimate and unexpected kiss scene during an undercover mission.
In this episode, the elite violent crimes task force carried out an undercover sting dubbed the “Monkey Operation,” aimed at capturing a ring of car smugglers. To lure the suspects, the team secretly used the Police Commissioner’s car as bait.
While Kim So-hyun’s character, Ji Han-na, was initially supposed to team up with Kim Jong-hyun (played by Lee Sang-yi), a jealous Yoon Dong-joo (Park Bo-gum) made the first move, riding with her instead. This subtle power play didn’t go unnoticed, especially by team member Shin Jae-hong (Tae Won-seok), who teased, “Perfect setup for romance.”
Tension escalated when Dong-joo accidentally honked the horn while trying to film the suspect with his phone. As the car thief approached their vehicle, Ji Han-na acted swiftly—climbing over Dong-joo and kissing him to divert suspicion. She even blocked the window with her hand as the flashlight hit the glass, pretending to be lost in a romantic moment.
Her quick thinking worked, with the thief backing off while joking, “Have a good time.” But the atmosphere inside the car remained charged. As Ji Han-na tried to recover, Dong-joo gently brushed her hair aside with a faint smirk, intensifying the chemistry.
Flustered, Ji Han-na quickly returned to the passenger seat, ordering, “Stop. Back to positions.” But Dong-joo’s smug grin hinted at a small personal victory, leaving viewers grinning along.
