As high schoolers, Yoon Ha Na (Kim Ji Yeon), Yoon Ha Ru (Jang Se Hyuk), and Jung Woo Jae (Park Seo Ham) were all close: Ha Na and Ha Ru as twin siblings, and Ha Ru and Woo Jae as judo competitors. As adults, Ha Na becomes an actress with Woo Jae serving as her bodyguard, while Ha Ru becomes an internationally-ranked judo athlete. When a stalker kills Woo Jae while he’s trying to protect Ha Na, the twins are left heartbroken at their friend’s death. But after a car accident sweeps the twins out to sea, they wake up in 2010 – and in each other’s bodies. Ha Ru and Ha Na must now navigate their swapped identities, their shared desire to keep Woo Jae alive, and the consequences of slipping back and forth in time - alongside Woo Jae and Ha Na’s developing feelings for each other.
