Jay Park (Park Jaebeom): A Korean-American currently living in Korea studying at college whose passion and talent for anything Hip-Hop has made him one of the most popular students at the school. A bit of a playboy attitude since he's closed his heart from the incident that happened years ago in the US. After seeing Tiffany at the school is wary of her to avoid any awkward situations in hopes of not being recognised.

Tiffany Hwang (Hwang Miyoung): A Korean-American who recently moved to Korea for studies and because her parents wanted her to learn about her heritage. Separated from everything she's ever known she moves forward with a smile ready to conquer everythingin front of her. Has a sneaking suspicion about Jay's identity not knowing who he is at first.
