Pyeswaeja(2000)

Pyeswaeja

Yi Myun lives with his father. Though he possesses memories of his childhood just like everyone else, there are times when he feels like a stranger in his own home, in his own skin. He has no friends at school, and his father is alternately too cold or too loving to be entirely normal.

What, really, is going on here, and why do random people who sometimes meet Yi Myun on the streets seem to know him as someone else?
