Sweet Enemy (2017)

Boh 100+ episode revege dramas with Very similar plots. Female lead goes to prison for a muder she did not commit. The revenge in YB is better IMO. The lead in SE is too nice and too naive.

Both are 100+ episode revenge dramas. Plots are similar: death of a child, crazy boyfriend stealing second female lead, etc.
