The main reason why I watch this is because of Suzy. I love Suzy so I want to watch this, but then I see so many people say they are disappointed with this movie so I'm really curious and watch this. I personally the story is really really great. I love the story a lot. It's not light love story but not deep as well. Just teenagers first love that has many difficulties. I love the cast. I like Suzy and the Sungmin Boy. I also like the older Suzy and the older Sungmin. I think all of them play the role really well. I really love that Sungmin Boy's acting I think he's really great ! Overall I think the movie is great but the ending ruin it all. I expect better ending but it turned out to be simple and realistic ending. I still think this movie worth to watch so I recommend this movie to everyone :)
