Wonderland, an amusement park in South Korea, still has every of its corners full of decorations and laughter. We still have Goo Seo Jin and Robin. But what happens if Jang Ha Na becomes their first love, but she forgets all of those memories that they've shared? Would they find the Jang Ha Na that they used to love behind the mask that she created?

A retold version of HJM, from Jang Ha Na's perspective...

Seo-jin and Hana are enjoying their happily ever after together, all thoughts of the past gone. However, everything changes when Fly Me to the Moon plays on the radio, sending Hana into a hypnotic state that Dr. Kang can't pull her out of. What exactly did Tae Joo plant in her mind, and why is he insisting that this isn't his fault?
