'It's okay, that's love' deals with mental health even though there is no autistic person. ML has mental health issues and FL will do everything to help him because she loves him very much.

These dramas are different stories but in both main female lead is a lawyer. In 'Undercover' FL is a mother of a son with autism and although it's more a side story, Yoo Sun Ho definitely nailed his role. Also in both series ML will do everything to protect FL.

Both films tell a story about:
- unfulfilled love;
- loneliness and longing for another person;
- emotionally broken people who try to survive in this world.

Both films are unforgettable, and the actors nailed their roles.

Both dramas are about love between older woman and younger man. In both FL is a mentor to ML and ML falls for FL. Also both dramas have some crime/political plot.
