This is for Uo-chan!

After a street brawl, a worn out Arisa is taken back to the Honda apartment by Tohru, where the calm lets her fall asleep from sheer exhaustion. She wakes when Kyoko comes home and stays for dinner, and from then on she keeps returning for Kyoko's advice while a real friendship with Tohru takes root. Arisa drifts back toward regular attendance and studying, even helping Tohru with schoolwork, though her old gang resents her going straight.

Their bond runs into trouble in public. A teacher spots the two chatting in a hallway and assumes Arisa must be extorting Tohru, only for Arisa to explain flatly that they are simply talking and for Tohru to answer the concerned questions with genuine confusion. Arisa realizes her reputation makes an open friendship costly for Tohru.

During a cooking lesson a classmate asks whether Arisa is Tohru's best friend, sending Tohru into flustered joy, while other students murmur that someone like Arisa could never truly be her friend and even suspect Tohru is faking a good-girl act. Overhearing this from outside, Arisa is stung not by the insults aimed at herself but by the damage to Tohru's image, and she coldly distances herself to shield her. Wanting a clean break, she tries to quit the gang and is nearly beaten badly until Kyoko intervenes, her old Red Butterfly reputation enough to scatter the attackers. Arisa leaves the gang for good, later meeting Saki and helping watch over Tohru after Kyoko's death. In the present she reflects on both women while cooking beside her father.

The title is drawn from a line of Tohru's, and this installment forms the second half of a two-part look at Arisa's past, adapting from the back portion of chapter 40 through chapter 41. The anime expanded many moments, among them Kyoko repeatedly opening her door to Arisa, the delinquents' beating, and a reworked closing where the three gang girls now idolize Arisa, one even cosplaying as her, rather than fawning over stolen photos of Kyo and Yuki.
