Hachiman finds himself coerced by his well-meaning student advisor into joining the one-member Service Club. There he encounters club founder Yukino Yukinoshita, a smart, attractive, walking superiority complex who looks down on the entire student body. These two negative personalities are quick to attract Yui Yuigahama, who's cute, bright, cheerful, and needs the Service Club's help to… bake cookies? Is this a recipe for romance or the precursor for a nuclear meltdown? Will there be cookies, nookie, or a reason for everyone to play hooky?
