If only things had come together properly. It didn't and that's what is wrong with this movie. Things aren't explained and it feels incomplete. The first part draws you in with the mystery about the wife dissociating. Bae Soo Bin gets your sympathy from the beginning. Then there is a shift to the other actor. You want to keep watching to see how things are explained but it only partially satisfies.

Saw this at the Imagine filmfestival 2021, usually in Amsterdam but now 100% online. As one fellow reviewer wrote: watching this is indeed "lost time" (one of the alternative film titles). I cannot explain how everyone can be so positive about this movie, with the exception of two fellow reviewers and me.

It is not a real detective, no whodunit in the traditional sense. Nothing is revealed in the end and we are left as confused as we were before the finale. I sat it out while waiting for a rational explanation, how the former cop maintains his looks and his own memories, though everyone sees the teacher in him, and he is treated accordingly. Intriguing, as it is exactly that same teacher whose death he was investigating. When the credits appeared, I was puzzled, but not in the positive and healthy sense after the usual detective story.

The acting is great but I hate it when I watch a movie to the end and understand nothing.
