There are relatives in the female leads' families that would do anything to get rid of the female lead. In Hide and Seek it is her Grandmother and in Inheritance, it is her mother-in-law. The difference is that in Hide and Seek, the female lead has backbone from the beginning. While the female lead in AHYI, grows to have a backbone later on.

I really love this drama. I watched this drama over and over again. It's a family drama and the cast are all good. You can feel that they're a real family. I'm not really into a long episode drama but if you're a korean drama fan this drama is a MUST. The OST's are great. Chemistry between Lee min jung and Jung kyung ho was really amazing!!! You will laugh and cry. Get angry with the other characters but all in all it's a very very good family drama.

it has a secret birth - hiding whose child is whose and then finding it all out later causing chaos
