The drama’s theme is a family that stakes their lives on the exam war.

In Korea, incredible things happen when the February exam season arrives.

Police cars come out to take the kids to their test sites! Getting into university is even more important there than in Japan.

The drama portrays, very realistically, overzealous tiger moms and dads and the children who suffer because of them.

When I listen to “It has to be you,” it sounds like it’s saying, “I’m going to get into that university.”
