I haven't ever written a review but I would really like to write one for this amazing kdrama. Before I started watching it, I was discouraged by some comments/reviews but I'm glad I gave it a go. First of all this kdrama is the saddest one I've watched until now. I bawled my eyes out almost every episode(and I'm not an emotional person at all). I've watched a lot and I mean a LOT sad melodramas and dramas but this one won the first place for me. It had so much potential and meaningful sayings/quotes about life and the point of living. I learned many new things and I'm really happy for this. "The one and only" even tho it was heavy I found comfort in it. Some people might get bored because they do not understand it's real meaning, since it is very deep and complex. I definitely recommend watching it, especially if you struggling in life or want to come across a different perspective of it. Both acting( every time the ml looked at her had me screaming, all his feelings were portrayed in his eyes ) and story was superb. If you put yourself in their shoes and understand the whole vibe/mood im sure you will like it.
