Ai Yori Aoshi - Season 1 Episode 8 Cherished Treasure

Tina decides to buy a ferret much to the chagrin of Miyabi. Since pets make messes, Miyabi says she doesn't want to make more work for Taeko. However, Taeko sees the animal and goes, "KAWAII" which ends Miyabi's argument. The ferret escapes confinement and heads straight for Miyabi, stealing her favorite pen. This causes her to chase the animal all through the house. Finally, Miyabi locks herself into her study and refuses to answer anyone. The ferret encamps outside of her door and then tries to get in by climbing up a grandfather clock to go into a small open window above the door. Unfortunately, the animal falls and gets stuck behind the clock. Miyabi aides the others in rescuing the poor animal and the ferret gets a name.
