The flow of the story is relly good but its relly detailed so you need to understand everyting. The casting is so good and all of them did so well. I like how the story of the 2 flowed in the movie though they gave an open ending. I dont really know if they continue to seoul or something but I wish the two male lead will meet, while watching the movie I just realized that, Indeed, Goodbyes that aren't said are the most painful goodbye, I was really hurt when hyun min leave like that but I understand his reason... I was ready to cry when seol was leaving because Its really sad that those people that are left behind wouldn't able to see you in a long time but yeah, in the movie they didn't continue what happened that night. I read a comment that the lamb that gave birth is a sign of hope so maybe ther is still a hope for their story, I wish they give us continuation. Overall I love this movie so much, I learned a lot!
