These two dramas have a lot of similarities-
1. mean/evil mother figure
2. an ordinary females introduction into a traditional and prestigious family
3. a mamas boy who has been controlled by his mother
4. suspicious deaths which are investigated
5. very packed full of drama episodes
6. traitors or backstabbing characters
7. an older senior character in the family
and much more
this drama is a lot shorter, amounting to 8 hour long episodes but it is very interesting and i highly recommend it. these two dramas are VERY similar.
