choppy editing, too rushed

it started good actually, but after 10 mins, it becomes a mess. some of the characters just pass by here and there. no development whatsoever.
i wish this was a drama instead. because a lot of things need to be explained better.

i mean EX and JX grow up as siblings. but after years of separation they fall i love? that last twist of illness? who did EX got married to?

the music was good, but it wasn't anything memorable.

I watch this for ZLS and i don't regret it. she did great with her role. but i really don't like the storyline.
