In Pantry d'Or, a small yet quiant pastry shop, three girls strive and do their best to run the establishment and like their catchprase, satisfy the customers' sweet tooth. Bae Joohyun stays behind the cash register and mans the counter, Son Seunghwan operates inside the kitchen and actually bakes each pastry sold and loved in the shop, while Kang Seulgi moves all around the place and helps in whatever is needed from serving the delicacies, wiping the tables or making the dough. These three girls are more than content with their jobs since they have been employees of the pastry shop for quite a while. Mrs. Kim, the pastry shop's owner and manager, is a very kind and fair lady, has real passion when it comes to baking and has treated the three of them very well.

All was well and pleasant.

Until, Mrs. Kim's son, Kim Junmyeon becomes the shop's new manager as it was his mother's wish, and ever since his buddies, Kim Jongdae, Kim Jongin, Oh Sehun, Kim Minseok and the rest of their friends has sort of made the shop as their new rendezvous. 

What would happen now?
