As Valentine's Day approaches, Axl takes Boss Co., with partners Sean and Darrin, to the next level by offering their services to help guys break up with their girlfriends. Brick becomes upset with Frankie when he discovers that she has thrown out all of the school artwork he made over the years. Frankie tells Brick she will always remember how she felt when he made her something, which is the most important part. Meanwhile, Sue becomes estatic when her ex-boyfriend Matt asks her to the school's Valentine's Day dance. As she's getting ready, Axl and friends overhear a message left by Matt saying he got back together with his girlfriend, and won't be taking Sue to the dance. Darrin ends up breaking the news to Sue, and says he'll go to the dance with her so that way she won't be alone. Feeling guilty over their business, Axl and Sean also go to dance and attempt to bring some of the couples back together, but end up getting chased away by a group of angry girls. Sue later thanks Darrin for being so nice, and he admits that he didn't take her to the dance just to be nice, and they kiss.
