I totally loved this drama, one of the best! I got greedy at the end and wanted more, i.e. what happened to his mother,etc.

The writer did not give light/leverage for the viewer to compehend/find what was being conveyed? Clues given w/no direction to where they lead; unlike the character getting clues in finding something from Su In. Does the present have pieces of the past? At the beginning the Yun wanted the door to be kept open (like Su In) needing the window open. Clues I come away with is CRYING, a PHONE (used by girl) brings the unexpected call with silence (is she the vision to the future message); The art work found in the LOCKER does it represent Su In? And what about Yun does the LIGHTER represent her finding the truth? I wish the viewer was given light to understand the entire message...and what is the connection between the 3? Are they all one in the same? The new girl made comments "When did you meet Su In" "Why did you do that to the painting" "You are the problem". Car scene:one cries then the other cries, does it mean there was only 1 child the other an imaginary one? A story unfinished? Well titled?
