Plot:

Kwon Megan and Lee Yuri are identical twins separated at birth. Yuri lives at House of Love, an orphanage in Tongyeong, South Gyeongsang Province, where the younger residents look up to her as a mother figure. However, she hides the fact that she is bullied at school by a gang of mean girls led by Krystal Jung, while teachers turn a blind eye.

On the other hand, Kwon Megan is the most popular girl at Segang High School, the most prestigious private high school in Seoul's Gangnam District. Megan's best friends are Choi Sooyoung and Im Yoona, and she shares a mutual attraction with Nichkhun Horvejkul, the school's star swimmer. They have been friends since they were 8.

Yuri and Megan look exactly alike, but only Megan is aware of the other's existence. Unlike the cheerful Yuri, Megan is prickly and secretive.

One day, on a school field trip to Tongyeong, Megan mysteriously disappears. At the same time, Yuri is unjustly expelled from her school and jumps off a bridge in a suicide attempt. Ten days later, the injured and amnesiac Yuri is mistaken for her twin Megan, and the latter's adoptive mother takes her home to Seoul, where she starts living as Megan.

Secrets get revealed later on when Yuri realizes she isn't Megan as she soon gets her memories back, but it is then discovered a body was found at the site of Yuri's 'suicide'. So she starts living as Megan as Yuri is now 'dead'. Soon, Krystal Jung joins the school and finds out Yuri is imposing as Eun ByuMegan and tries to make her life miserable again, but Yuri has changed and is now a different person from before.
