On the other hand, the second daughter, Park Yoo-ha studied hard in medical school and finished her intern course, but sacrifices her dream to become a doctor in order to marry her love, who is from a rich family.

Eun-tae is not interested in marriage because he believes he is like his father, who places priority on his medical work over family.

The "Hope Solidarity Union" (희망연대노조) recently expressed concern about the well-being of the drama's working staff.

According to the union, the production staff members were exposed to a harsh working environment: they were overworked but their salary was too low.
