|Episode 5 - Tohru's Real World Lessons (She Thinks She Understands It Already)|
Tohru is watching TV to learn more about humans, and then decides to go and sneak into Kobayashi's work and spy on her. She starts getting mad at the boss for yelling at Kobayashi so much, and makes him trip a few times. After work, Kobayashi calls out Tohru, revealing that she suspected her presence all along.
Fafnir is curious about the human world and wants to live here for a bit, so Tohru helps him get all the paperwork done. Fafnir wonders why Tohru likes this world so much, and asks her if she'll still be able to kill humans when she returns to their own world... but Tohru says she doesn't want to ever return, even after she outlives Kobayashi, because she's started to love the human world that much.
Tohru gets the idea to go and ask Kobayashi's friend from work to let Fafnir live with him... I think she starts to realize it's an awkward thing to ask, but then the two of them get along so well because of their interest in video games, the guy is just like "okay sure".
Tohru wants to start learning some of the hidden skills that humans have, so they start training in the mountains. Kobayashi is like "why do you care about this, you can already do tons of stuff that humans can't"
