Honey's Three Bitter Days! is the 12th episode of the anime series. Honey gets a cavity; the number one rule until the cavity is fixed being, "No Sweets." Growing ever more agitated, he eventually snaps and takes his frustration out on his cousin and best friend, Mori. The two experience an almost unheard of event between them - an argument. Mori is devastated, but Haruhi gets to the bottom of things and the friends are reunited with a bit of Suoh assistance. The concept of moe is introduced and though Haruhi questions its value, Renge and the rest of the guests think it's marvelous.
