Well developed story line, beautiful acting by the characters and excellent character interaction makes this show a beautiful drama for me. This show ranks top 3 for me (only preceded by It's Okay to Not be Okay, and Descendants). I loved the story of their parents, and its impact on the main character's lives. I loved the sad tinge underlined throughout the show that makes you think how the character's lives would have been different had one character from 1980 made a different decision. I love the how the past meets the present. And despite my least favorite genre being romance, I absolutely love the chemistry and romance between the two leads. Healer had everything, and just as a the title suggests, had a healing effect on my otherwise lonely life. It's relatable and fantastical. It is everything I wanted and more. Just go watch the show. Totally worth it.
The only complaint I would have is that the ending is a bit quick/rushed. But it is a satisfactory ending.
