This movie is very wonderful. I discovered this movie at newasiantv because I'm a fan of time travelling dramas that's why I tried to watch it....I love how the problem is solved but not completely.....It's best to watch when it's raining...YOLO guys.....Spend your youth without regret is the best way to make your future be happy...Overall, this movie is marvelous and well-made. It reminds me of a movie mmm.. I think it's suddenly 17? I'm not sure but this movie is great! The actor also reminds me of ong seungwoo a little....
