You are an illegal race car driver in Seoul, known for your street smarts and your modified car and for your workshop called 'Jade Dragon'which lived up to its nickname on the streets'White Dragon'.Jennie is an undercover agent working to dismantle a dangerous illegal racing ring.Your paths cross when Jennie,disguised as a racer,challenges you to a race.The attraction between you is immediate,but your worlds are dangerously different.As Jennie delves deeper into the investigation,she discovers that you may be the key to bringing down the criminal organization.However,her feelings for you have complicated her mission.Jennie really wanted to arrest Zen Kobayashi, better known as Baku,he had been your enemy on the streets for a long time,but he was like a ghost to the police.Jennie and you had been dating for months without you knowing her true identity.Your team of runners and partners were made up of:Choi San,Kim Hongjoong,Kim Jiwon,Song Minho,Kim Namjoon and Min Yoongi.You only discovered Jennie's true identity because you asked Yoongi to hack her and so he did knowing Kim's entire past.

—Hon,listen,I know I messed up,I'm sorry for that.I know I fucked up.–The brunette told you with sad eyes as she watched you seemingly irritated by the information.But her standing there in your favorite shirt and just a pair of Calvin Klein underwear and looking sleepy looked so right.

—I love you and I want to be with you,my coworkers and even my superior knows that I'm getting involved with you,I handed over my gun and badge this morning.And besides,I'm pregnant.–Jennie said looking at you nervous and fidgeting with her fingers.Jennie wasn't even sad about losing her job, the Seoul police station never valued her and in general they despised her just because she was a woman.Jennie had only accepted the case of infiltrating the street races to prove that she was a good cop.But you also knew it would be even worse if Zen or anyone else found out who Jennie was or what she worked with.
