Well,,, you might wonder why I choose these drama as a recommendation…

But I would like to point out one thing which is…
Jung Dahee and Hyun Sooah character…
Both are tooooooooooooo similar…
I’d say it might be a ???? (inferiority complex)… which… might be one of social problem (according to what I’ve seen in a lot of drama and series tho)

This type of character might be a subject for research tho… ??

Although not obviously similar, the ML in both of these is a doctor and a criminal, and both shows have you debating the morality of his character. With a partial prison setting, and a partial medical setting, both shows hold a high suspense, psychological tension and interesting premise. I highly recommend both of these.
