The City of Passing Time (2022)

I'm not halfway through yet, but it's reminding me of Mr. Sunshine in quite a few ways.

In both dramas, the protagonist is a strong woman with her own ideals who is not guided by anything or anyone.

-Both are republican drama
-Both have smart FL
-FL tried to get closer to ML with a bad purpose
-Both have a love-hate relationship story
-Both have the same main plot. It's about revenge

Both are Republican Era dramas in which the FL approaches the ML as part of her revenge plot of taking down his family who destroyed her family.

Both feature a student/teacher romance between the older FL who tutors him and the younger ML who falls first. In both dramas, the ML has a strained relationship with his father, and his mother is no longer living.

Full-length drama with similar plot and characters.

Similarities:
- Simp ML with a hot bod and smouldering gaze
- Revenge-driven & mature FL
- Republican era
- Steamy kisses & explosive chemistry

both have similar vibes:
both about revange of the female lead
both rich man, weak women
both smart women
both male lead have people who follows their orders
both have romance in it.
if you felt something was missing in COS you might find it in the plot of CR
