Destined With You is a South Korean romance drama running 16 hour+ episodes.

Lee Hong-jo (Jo Bo-ah who was the female lead in Military Prosecutor Doberman) is a civil servant recently transferred to Onju City Hall working in the parks department where she starts disadvantaged because her new boss she reported for bribery (which was a misread on her part) and that his dislike leads her two co-workers to shun her leaving her alone (she has no parents).

Early on she's tasked with up keeping a specific park (think more like wilderness park not a city park) and her first problem is getting an abandoned shrine demolished after someone died live-streaming on the site. It takes her a bit of doing but she eventually does it over the objections of current land owner Jang Shin-yu (Rowoon). Shin-yu subsequently leaves his company (a big land developer but unscrupulous) and joins Onju City Hall as the lead lawyer.

While the shrine was being bulldozed Shin-yun found a buried box which his prescient aunt says belongs to Lee Hong-jo. Inside she finds a spell book from her Jeseon-era ancestor. One of the spells can break the Jang family curse, of which Shin-yu is starting to feel the effects (a brain tumor that is causing neurological effects like shaking hand). It takes a while to convince Hong-jo to try it but she does so. She then uses a love spell potion to captivate Onju City Hall hottie Kwon Jae-kyung (Ha Jun), who is the mayor's adviser.

But Shin-yu accidentally drinks the potion so the next few episodes are trying to reverse the effects since neither one wants a romance with the other. Of course eventually Shin-yu gives in as his rational mind comes to agree that Hong-jo is the one for him. Another complication is Shin-yu's girlfriend Yoo Na-yeon (Yura who I just saw in a supporting role in Forecasting Love and Weather). Na-yeon is the mayor's daughter and has been angling for marriage for some time now but Shin-yu didn't really love her even before the love potion.

While Na-yeon tries to sabotage any budding relationship between Hong-jo and Shin-yu the latter picks up a stalker who is much more sinister as the series goes on. There is also a whole episode in the past showing how Hong-jo's and Shin-yu's ancestors fell in love and then he betrayed her (for good reasons I suppose) and the stalker's ancestor is also there.

It's a fairly good romance. It is annoying that Hong-jo keeps doing things that put her in danger (apparently even though you know there's a stalker and know who he is going out alone to a wilderness park doing your job is fine). It's unfortunate that Na-yeon has to be the bad guy who bullied Hong-jo in high school and is just continuing being a Mean Girl, especially as there is a perfectly good bad guy in the stalker (played by Ahn Sang-woo). Shin-yu's illness is barely used.

Interestingly no other romantic subplots. Closest is Shin-yu's parents: Father Jang Se-hun (Lee Pil-mo) is sort of constantly belittling his wife, former actress Song Yoon-joo (Jung Hye-young) to the point where she files for divorce and now he has to win her back. But that's fairly late in the series, takes a while to get to the divorce notice, then is quickly resolved.

Not in my top K-romance drama series but still very enjoyable.
