Futaba Igarashi, an office worker, navigates her career, life and love while growing closer to Harumi Takeda, a senior coworker who always makes fun of her.

It's almost Christmas; after much deliberation, Futaba decides to get Takeda a gift because he's always looking out for her, but finding the right time to give it to him is another matter.

Valentine's Day is coming up, and the guys in the office are hoping to get heartfelt chocolate instead of courtesy chocolate from their female co-workers.

Everyone attends a cherry blossom viewing event; Futaba and Harumi get talking about Natsumi's friendly nature.

It's Golden Week, and Futaba plans on spending the holidays productively, but when she sees a scary TV show and freaks out, Takeda comes over to keep her company; Kazama and Sakurai go to an aquarium and meet a dolphin that shares his name.
