Once in your life you meet someone who changes it completely. Whether you want to or not. Sooyoung was looking for change in the big city in her drafty little apartment and lack of a job. Her neighbor, the anti social night shift working Jessica, is her only friend. The two of them sling hash over a bottle of wine occasionally, both talking about how much they dislike other people. Then there's Tiffany. Tiffany left home at a young age, dropping out of high school after her sister's death. She came to the city to become a painter and unbeknownst to the other girls is living on the same floor in the same apartment building. Tiffany is having struggles of her own selling paintings and deciding what her relationship is with her best friend from art school Taeyeon. When Sooyoung and Tiffany meet it's a mixture of negative feelings and wine. But soon four girls are brought together and they discover that Mondays might not be so bad after all.
