The Big Twist You Need to Know First

In the previous episode, a shocking twist was revealed — Sunwoo Chan had been exchanging messages with Song Ha Ran on behalf of a different “Chan,” her boyfriend Kang Hyuk Chan — and not himself.

Rather than walking away from the guilt, seeing Ha Ran struggling to overcome her grief after the loss of her boyfriend, Chan made up his mind to help her find happiness again and offered her a “three-month neighborhood friend trial” before his return to the United States. MSN It’s the kind of quietly noble gesture that this drama does perfectly.

What Happens in Episode 3?

Ha Ran and Chan embark on a danchung (traditional Korean decorative painting) tour as part of their ongoing animation collaboration. Ha Ran is taken aback by Chan’s choice of outfit — but his traditional garb and infectious energy quickly make him popular at the palace.

Then comes the emotional gut-punch: while Chan briefly steps away, Ha Ran strolls alone through the palace and suddenly freezes in her tracks. As she stares at something in the distance, her eyes begin to redden with tears, as if she’s just witnessed something she hadn’t expected.

The real breakthrough happens after: as Chan gazes at her with eyes full of concern, Ha Ran finally opens up about the long-hidden feelings she’s been suppressing. In turn, Chan shares his own story of having once been caught in the harshest of emotional winters — resulting in both of them learning about one another’s wounds and pain.

Two broken people, one unexpected palace afternoon, and the slow thawing of a winter that’s lasted far too long — this is the emotional architecture that makes Korean drama so universally beloved.
