The leads are reunited while they are older and become colleagues

- Female lead is both a hardworking lawyer.
- Domineering male lead
- Cute height difference
- cohabitation

in this drama the Male Lead is also in love with the female lead since they were children. The difference is that the FL also was in love with him.
In both dramas the adult FL are hard working and independent, as children they were leading the relationship with ML.

Both couples are very sweet and devoted to one another.
Although there is a guy who likes the female lead- he always stays back and doesn't bother the couple's romantic relationships.

A lot of the scenes are around medical cases and inside a hospital.

The guy is a little cold with the girl at the beginning.. but warms up quite fast.

Both dramas have unusual bromances between a very young-looking uncle and his nephew.

They are both romantic C-Dramas where the main people are either doctors or lawyers. They both seem to have met before the beginning of the drama.
