A typical day for Mo Hani is quite mundane; after finishing her nine-to-five job, she shops and then relaxes with some comfort food. Sure, she doesn't have a ton of money, but that is not what matters. She has her friends, her bachelorette lifestyle, and a stable income. Conversely, Kang Seonjun, Hani's best friend's younger brother, is barely making ends meet—juggling numerous part-time jobs and sleeping in his university club room. Although he wants to one day have a family of his own, he believes that having financial security first is necessary to reach that goal.

However, after the two spend a drunken night together, Hani discovers she is pregnant. Worried about Seonjun's circumstances and what her best friend will say, Hani is unable to tell him the shocking news. Subject to the whims of fate, Hani and Seonjun must simply handle what life throws at them, all the while hoping everything will work out somehow!
