Kyungsoo is an educated Korean man trying to make it in New York. Unemployed, he sings at a cafe with his roommate Chanyeol to make rent. Until one day his heart catches on one particular coffee lover and his entire personality suddenly becomes a problem in his pursuit for love.

There's a new circus in town and Chanyeol should've thought better than to give in to his daughter's wishes.  

Shin Hyorin was a studious, oblivious, university student. But when her roommate forced her to stalk her crush who works at Starbucks, Hyorin had no choice but to comply. The affiliation with that cafe compelled her to stay, but what happens when she finds herself more reasons to return other than her love for coffee?
