I'm soft for these kinds of stories, they really had me at "based on a true story" TT_TT
Sawada was the true mvp here! he had so much genuine feelings, his happiness for other people's good news, and his heartache for their sad news was so heartwarming and he did so much for Bae Jae Cheol..

Bae Jae Cheol was kinda really selfish (maybe they made it more dramatic for the movie), but his wife also had her own problems and he never really tried to help her. she was an angel to put her own problems aside and stand by him :) looking at some real videos though, Bae looks like a sweet guy.
and they might've not fully added her story for time value ;)

also, I wonder if Misaki was also based on a real person because I shipped her with Sawada xD
I'm a huge opera fan so I loved the soundtracks, but the audio quality was not that great, and sometimes the background singing was louder than the dialog, plus they also had such a diverse cast, and with their accents it was kinda hard to catch everything but since they added korean subs it was only a problem for me ;p
