Some time ago I watched a movie Japanese drama trailer. I can vaguely remember the story but I think there was a girl looking for a mysterious guy and this guy is either missing or dead but everyone around him knew him (like he was the kindest person in town or something). I believe it was a Japanese film, and the genre is probably in drama/slice-of-life.
I've forgotten most parts but if you have any idea I'd love your thoughts! Thanks!
