Kim Taeyeon and Tiffany Hwang had been bestfriends for 7 straight years. Both of them had lived together in a dorm 4 years ago, and even though  they are living seperately from each other now, they are still very close and they never forget to get in touch with each other everyday.

But one night, something happened. Tiffany got dumped by her so-called 'boyfriend', and Taeyeon just found out that her boyfriend was gay so she broke up with him. Taeyeon and Tiffany got both of their hearts broken, and they decided to take away their pain through drinking some alcohol. So the both of them went to the same bar and unexpectedly met.

Taeyeon and Tiffany decided to drink with each other, since they are both broken. But what if something weird happens between them? What if they will have a one night stand for the first time? 

And what's worse, when they woke up the next morning, they found a little 2 year old baby boy lying between them on their bed after their one night stand encounter from last night.

Will Taeyeon and Tiffany be able to handle their following situations? First, their one night stand. Second, here comes a baby who claims to be their child?!
