The finale plays out as an elopement and a wedding. Shizuma declaring her love in front of everybody, Tamao accepting that Nagisa isn't really hers and pushing her (literally) away... and all the happy endings.
Hikari ends up singing too early in a choir performance and publically humiliating herself in front of the whole school. She thinks about quitting choir due to the humiliation, but Amane talks her out of it, ending with her taking her back to the dorms on horseback.
After Amane recovers from her amnesia, the next morning she and Hikari are shown waking up together, having just made love and looking utterly blissful.
In short, Pretty much anytime Amane and Hikari are on screen together.
Chikaru comforting Hikari over Amane's amnesia... with puppets.
