Narumi and Hirotaka went from being otaku friends to being in a relationship. However, Narumi feels awkward and starts avoiding Hirotaka. When they notice what's going on, their senior coworkers Hanako Koyanagi (a cosplayer) and Taro Kabakura (a mild otaku) try to give some advice.

Hanako and Kabakura get into a fight when they go out for drinks after work one day. Hanako starts to worry because she thought that dating Kabakura would be easy since they were both otaku. Narumi is reminded of her own relationship as she watches Hanako and Kabakura.

It’s the end of the year, and Christmas is coming up while everyone is busy. Hanako, who tells Narumi that last year’s Christmas was the worst ever, isn’t expecting much this year. Meanwhile, Kabakura is busy at work...

The group decides to get together to play an online game. However, while they wait inside the game for Hirotaka to join them, a rare enemy suddenly appears! Narumi, Hanako, and Kabakura aren’t strong enough to beat the enemy themselves and find themselves in a tight spot when suddenly, a savior comes to the rescue!
