What would you do if you found out that you were, in fact, a character in a comic? And an extra character on top of that? Change the course of the story, obviously.

A story of love and friendship between five high school students from Seoyeon High School. Lee Ha-Min (Seo Ji-Hoon) appears like a bright person, but there is also darkness within his mind. Han So-Mang ( So Ju-Yeon) is a warm-hearted person, but she is also quite timid. Lee Jae-Min (Kim Min-Kyu) is a popular student with a painful past. He is kind to everyone around him. Yoon Bo-Mi (Kang Hye-Won) is a sweet, model student. Choi Jin-Young (Yoon Hyun-Soo) loves playing games. He can seem unfriendly and has a delicate personality.

Cha Su-yeol, a police officer who has long despised his mother, the notorious 'Mantis' serial killer, must reluctantly turn to her for help when a copycat killer emerges.

Ha Yoon-seo has worked hard her whole life: after raising her younger brother alone, she is now a marketing manager at a credit card company. Her life takes a dramatic turn when she discovers that her boyfriend, Seo Ju-won, is the heir to the family that owns the company! Upon learning of their relationship, Ju-won's mother offers Yoon-seo money to break up with him, and Yoon-seo accepts. However, Ju-won is determined to win her back and will stop at nothing to reclaim her heart. Can Yoon-seo and Ju-won overcome obstacles and find their fairytale ending, or will reality tear them apart?

Imbued with the power to grant wishes, a cynical nine-tailed fox's life takes a turn when she encounters a soccer player — altering both of their fates.

Born in 1981, So Won should be in her forties now, but when she became twenty in 2000, she encountered a witch by chance. So Won was cursed by the witch because she turned down her favor. The curse was "to live as a twenty-year-old woman for the rest of her life." At first, she thinks it will be a blessing but soon starts suffering from the pain of losing her beloved ones and her life re-setting every year. One day, So Won happens to spot the witch in a photo, so she heads to the resort in the photo's backdrop. To lift the curse, she sneaks in as a resort staff and meets Kang Hyun and Sang Wook there.
