On the latest episode of SBS “Rooftop Prince,” Park Yoo Chun and Han Ji Min grew their love line by sharing a fun time together. They played a game of “ding-dong ditch,” ringing the doorbells of their neighbors and running away, in the area where Han Ji Min snapped a family photo 25 years ago.

At one moment, they almost get caught by the owner of the house, but the two quickly run away again, successfully ditching the owner. Relieved from the chase, Park Yoo Chun and Han Ji Min laugh out loud and giggle along the way, growing their affection for each other.

Meanwhile, at the end of the episode, Park Yoo Chun appears to share a kiss with Han Ji Min, while sitting on the ground, creating an intimate “stairwell kiss” scene. It’s unclear how the storyline will develop at this point, but Park Yoo Chun and Han Ji Min sure seem to be something more than just friends!
