Tohru's finally gotten the hang of her maid duties. Suddenly interested in what Miss Kobayashi does at work, she heads out to observe. There she watches how everyone relies on Miss Kobayashi and falls for her again. However, there's also a boss being mean to Miss Kobayashi, which makes Tohru very angry... Out on the town she runs into Fafnir from the other world. Since he says he'll be living in this world too, Tohru winds up helping him find a place to live?!

It's Kanna's sports festival. However, when she learns Miss Kobayashi is too busy at work to come, she sulks. Miss Kobayashi wonders why she'd want her to come so badly when she isn't Kanna's parent, but Kanna already views her as one. Even Takiya tells her, "You should decide based on if you want to go, not if you can go." Finally, the day of the sports festival arrives. As a dragon, Kanna should have overwhelming physical prowess, but...?!

On Valentine's Day, Tohru attempts to give Kobayashi some chocolates containing a love potion, but she quickly sees through her plan. However, Kobayashi ends up eating some of it after mistaking it for chocolate Kanna received, although the love potion gets cancelled out by some alcohol that was included in the chocolate. Later, Makoto invites everyone on a trip to a hot spring inn, where Tohru gives Kobayashi some regular chocolates.
