My favorite korean movie

I watched it in 2020 and it stayed with me. I like rewatching it from time to time.
This movie is really amazing. When I finished watching I had to sit down and think.
The story is ususual compared to other movies of this genere. It puts bigger focus on the characters. Espacially two main ones, Jaeho and Hyunsoo, make the impression and their actors, Sul Kyunggu and Yim Siwan deliver a stellar performance.
Definitely recomend it.
