So I’ve not watched a J-dorama in years but one of the last ones I watched was Unnatural back in 2018 starring Ishihara Satomi. It’s a forensic drama that has a clinical emotionless female lead tackling weird deaths with seemingly natural element but in truth has unnatural causes that she needs to solve. A K-drama adaptation was announced in 2022 but went nowhere and now has been revived with news that Yoona is in talks to headline. I doubt many K-drama viewers have seen the original so doing the same cases as is won’t be a problem because the stories are interesting and I can totally see Yoona playing the role lead well.
