From all my watched dramas, this is the only one drama (cdrama) I would give 10/10 without even thinking about anything. This drama has everything, what should have best romcom - top actors, top scenario, top OST. Spending your time to finish all 40 episodes will be great opportunity to see, this drama isn't like other sweet romcoms. That's why I don't recommend it as your 1st drama. I really don't understand, why at all here it does have only 7,9/10. This drama, no matter how I tried, made me finally crying as only one from all cdramas/tdramas/kdramas. That's why this is special drama for me. You can ask, why I gave 0/10 in rewatch value - that's simple. You'll probably not want to rewatch this drama anymore, because it's emotional masterpiece. If it's on your watchlist, after watching it feel free to send me message, if you want to discuss about Waking Love Up.
