Both are mini series about love. Differences: each episode of KARA has a different story, while "Love Cells"continues with each episode. Although I prefer Love Cells over KARA, both are quite good.

From the same writer/PD team. Both drama has similar styles but different story. Same lead actor for both dramas.

I've written this recommendation before earlier in the series of Healer on how I thought CH and Healer have the same feel to each other initially. So now I'm here to edit and correct myself... Yes they do initially, but after episode 3 or more of Healer, I've come to realised that these 2 are very different dramas in their own rights. CH has great action scenes and delves more into the revenge-plot. Whereas, Healer isn't about revenge at all. More time is given into character development which makes each character much more layered. Healer has more OTP moments which makes me love and it isn't solely focused on full-on action (although I do love the action here). Similarities between these two dramas would only be the same lead actress and the action aspect, and then the two story goes off quite differently. PMY plays a very different character between these 2 to the point where I almost didn't recognise that she's the same girl for both dramas.

There's no dragging or boring bits for both dramas - each episode constantly keep you on your toes and wanting to know what happens next. While both have serious plots there are just enough comedic and romantic elements in between them for a more enjoyable watching experience. Healer of course has more romance/OTP interaction ? If you love one drama or the other then I would recommend both. I thought I should clarify since there were a lot of comparisons between CH and Healer.

Both are about revenge dramas with very good story to tell each. Our heroes have tragic pasts which haunts and drives them.
