I would rate this K-Drama as 6.5 stars (rounded up to 7), with little that stands out either positively or negatively. It was a pleasant, if generally tepid watch, with nice scenery, acceptable script, and a story and characters which were interesting, but not compelling enough to produce a lot of buy-in (for me).
The one noteworthy point was the ending, where the writers made an obvious effort to tie up all the loose ends for a clear-cut (if slightly unrealistic) conclusion. In short, if you like stories where justice is served, and the power of love changes people for the better, you might go for this one.
ROMANCE RATING: 7/10 * * * The romance in this show generally stays in the "warm fuzzies" category, with 4+ kiss scenes featuring gentle kisses or brief pecks. PHJ and JBA have believable chemistry together (though IMO it could have been even better). Sadly, the only real sexual tension was in a heated, pre-dating kiss scene where the leads are using their heart rate to prove how unaffected they are by each other. It would have been super spicy if not for the sound editing, which failed to adjust the BPMs and therefore made the intent of the scene confusing/ distracting.
