One day, there's a guy named Sim Jaeyun (called Jake) at Hana Seoul High School (popular yet rich high school). He's a hot, popular guy at school. All the girls students like him, except for Park Giselle. She's a student there too. She's really sweet, pretty, popular and smart. All the students likes her too. But? Giselle and Jake were enemies and rivals since elementary school (they were at the same school and class from elementary until now, fate). Now, they're at grade 2 high school (11 grade logically).
