Like, some drama's out there, Spring Waltz, in the starting episodes, it has some explanation of what happened to Su Ho during their past. More like flashbacks or something.

In times, Spring Waltz will make you smile, laugh and surprised in its own way. It has great music(whether you like classical or not), a nice plot and some really good and good-looking actors.

Overall of that, If you're into romance drama's this is really a recommendation for you to watch. Shed a tear if you must(Yes, it may happen.) If you're into the beauty and hotness(?[lol]) of the actors, this is a good drama to watch. But be warned, I will not promise that you'll like this drama very much like I did. Every person has it's own opinion, and I wrote this review for my opinion. So Enjoy~!
