1-3) Gozen Reiji ni Kuchizuke o
Aoki Karin has always wanted to be a bartender because of an American movie she watched when she was a child. On her 20th birthday, her friends take her out to a bar to celebrate. There she meets Shiino Takumi, who is much cooler and more handsome than the bartender from the film. Alas! Karin believes she has found the one... until she finds out that maybe she jumped into this a bit too fast.

From Shoujo Addiction:
Koga Nana is the new office worker who's really terrible at this kind of work. Since she's always making mistakes, she feels down more often than not. But she keeps on working hard because of Shibano-kaichou <3

One day, they go out for dinner together, but it turns out that Shibano can't hold his drink, and he gets drunk after just one glass of beer. With no other choice, Nana can only take him home with her.
