Erika talks to her friends about boyfriends and romance, but in all her sixteen years she's never actually dated anyone. She thought her lies had reached a limit until one day she takes a surreptitious video of a good looking guy she saw in town. When the loner Hachiman Hikigaya is coerced into joining the "Services Club" run by the smart, attractive, and stuck up Yukino Yukinoshita, it's a recipe for disaster! But we haven't yet added the third caustic ingredient! Bright and cheery Yui Yuigahama needs the Service Club's help to bake cookies. It could be a recipe for romance. It could just as easily end in a nuclear meltdown!

Desperate to fit in, Erika convinces a nice-guy schoolmate to pretend to be her boyfriend. But she soon learns he's not as kind as he seems. In order to avoid being a loner in high school, Erika shows her friends a photo she took of a random hot guy and claims he is her boyfriend.

Erika is proud to let her friends know about the relationship she has with her not so real boyfriend. Living the lie, Erika makes up this guy complete with picture. Little does she know, Sata Kyouya is a sadist and is in her grade at the same school! Marin and Tezuka only talk about their boyfriends.
