Jingi was just 1 year away from getting out of prison, but he couldn't even make it in time to see her one more time, and now he never will...
Jingi being buried in the cold snow is such a sad portrayal of his grief :'(( it's so quiet.
He's been in prison all this time never seeing his mom, but he dreams of her very night, and Myeong-il even encouraged him to greet his mom one day once he was out of prison.
