Harmonium

Both movies show a family who is grief-stricken by a horrible incident involving their child. A young man who is connected to that incident begins to work for the family. The endings are very similar in scenery and writing.

If you are after a Soredemo Ikite Yuku style movie with tense situations and masterful acting that will haunt you long after the credits roll, Harmonium is the movie for you. Must watch.
