Story: Usual timeslip plot with confusing epilogues but otherwise good story development. I kept getting amused how they applied the timeslip theory here. Nothing dragging, nothing irrelevant. Screen time efficiently used. Plot well-arranged. Acting/Cast: Perfect! Good chemistry for the main characters. I didn't expect Yoobi to have good chemistry with Minho but they did. Music: I like that the music also complemented the web drama (Follow Me Down OST from Alice in Wonderland). Rewatch value: I watched a few episodes again. It's not a long story and not dragging so I can watch it over and over until I figure how to connect the epilogues to the episodes. Overall, a must watch for those who love light drama with slice of life, school life, time travel genre. I expected a longer episode 10 though but, as with a few of the Kdramas I've seen, most endings seem to make me feel like there are missing elements to conclude the story.
