Knowing Lee Seung Gi and Moon Chae Won, I have already expected that they will present a superb movie.. and after watching it, I had guessed right. Moon Chae Won brought out a magnificent spontaneous acting as Hyun Woo. Other supporting characters were a revelation too. Lizzy, Hwayoung, Lee Seo Jin, Jung Joon Young... even Ga-in's cameo was perfect! What gave me a surprise was Lee Seung Gi's performance. Seriously... I doubt that I'll love Joon Soo if someone else portrayed him. It was a topnotch performance! I cried hard and was touched. I love his character the most. Their chemistry is also amazing; since they've been on Shining Inheritance before and remained good friends, I think it was easier to create for them. Overall, I had a wonderful, precious time watching it. Highly recommended to everyone! :)
