You love About Time? Eternal Sunshine of the Spotless Mind? Kimi no Nawa? The Girl Who Leapt Through Time? Someday or One Day?
And you love real romantic comedy series that has depth and is both plot and character driven, never boring from the first episode until the finale, acting masterclass by the cast, exquisite directing and writing, genius cinematography, best ending for a kdrama ever in the history of kdrama (I'm being so serious right now), then this is the one for you.
