A chance encounter with an alluring American Music Producer suddenly turns Cha Min-Jun's world upside down. And as the days go on, and he readies to perform his duty to his country, his mind is elsewhere, imagining how he could seduce the beautiful American girl.

Luisa "Seven" Fernandez is tired of having doors firmly shut in her face, so she packs up and goes to couch surf with her best friends in Seoul. And it's there that she inadvertently meets one of Kpop's biggest stars in a bar's bathroom in Itaewon.

For the happy-go-lucky, quick-witted, no strings attached, Seven, meeting Min-Jun can't come at a worse time. Not sure where her professional life is going, and seeing as not much is happening in Seoul, Seven makes a drastic decision that affects them both.

While Min-Jun and Seven try to come to terms with events that bind them together, they also have to race against the clock before Min-Jun's fans turn on him as news of his current not so single status is splashed across Social Media. Will the secrets that unite them help their budding relationship flourish, or will it all be for nothing?
