Kahogo no Kahoko is a light hearted, less suspense filled version of Okaasan, Musume wo yamete ii desuka? Similar aspects include a very protective mother, a clueless daughter, a boy from the "outside" and the outcast father. I really enjoyed both drama and recommend both. I would like to say that the mother is not as "psycho" in Kahogo no Kahoko, she is very controlling however she has her good sides

I believe that Delicious Destiny is a remake of You are the Only One. Both follow similar plots, the main male lead being a chef and female lead being a food "critic". Both also have a character coming from a foreign country to find his father.

Both films have a similar context but different reasons for killing. In Confessions the teacher performs acts of revenge towards students as she suspects that some may have killed her daughter. Whilst in Lessons of Evil, he kills students for his own sake.
