Let me start of using the fact that I rarely review dramas. I only review them when they are on their extremes; extremely good or just plain horrible. This drama is of the latter.

Someday or One Day, tells a story in a non-linear fashion, thus making things hazy and confusing, yet still wraps it up with the viewers fully understanding the story. Each second is very special in this drama, it is not draggy, non-predictable and really wholesome. It wraps it up by making each character have their own little conclusion, each persona have their struggles overcame with.

The OST, "Miss You 3000" also connects very well with the story, it is quite uncanny actually, seeing as how it manages to spark up the correct lyrics on the correct scene.

It amazes me how this drama is very tactile, there are just too many details too cover to remember each one, but what I can assure you is, no matter the going; please finish the drama, as you'll never regret it.
