Both are romantic medical dramas dealing with comforting people in pain and during the end stages of their lives. In both dramas, the male and female leads have experienced life-altering tragic events, which they feel guilt-ridden about. Both male leads have a nemesis who is hell-bent on destroying them do to misplaced anger and beliefs.
There's not much plot similarity, but the two dramas are closer in terms of their "vibes" (especially with how they combine food and healing, and with the warmth in their "patient stories"). In Unmet, both the episodic stories and the major plotline have been given a more delicate, realistic (and yet, more optimistic) treatment with beautiful storytelling. In my opinion, Unmet is not so much a mystery as it is a human drama/ romance (and a VERY GOOD one at that). I hope this helps anyone interested in watching Unmet with what to expect from it.
