After confession story and an original one, not the epilogue scene from the PSP game.
It was New Year, Kazuya is on his apartment and then a guest is coming. It was Mai, wearing a yukata.
They decides to go to the shrine for praying later, waiting for Kanon, so Kazuya brings sweet sake for drink. Mai likes it very much. They then playing karuta to kill some time. Mai wins the first turn, drawing a moustache on Kazuya's face but after that Kazuya wins the next turn. He says he'll draw the punishment on Mai later until the whole game end so they continue to play. But Kazuya always win until the game end so her punishment is stacked. On her mind, Mai is thinking Kazuya will draw her punishment all over her body
Kazuya doesn't have the heart to draw the punishment on Mai, making Mai happy, she then hug and push him over, smiling and squeezing Kazuya's cheek against her. Kazuya think Mai's being weird and he sees both his and Mai's cup. Turns out since it's so delicious for her, Mai even drinks Kazuya's sweet sake. Kazuya asks her if Mai is weak against sake (even the light, sweet sake) but Mai is offended because Kazuya is still seeing her like a child. She then hugs Kazuya, saying she is already an adult and she's waiting for Kazuya to "take her into the unknown world". But short later she's feeling unwell so she excuses herself to the toilet D:
They then go to the shrine with Kanon. Kanon says her praying loudly, Kazuya and Mai says that the prayer shouldn't be said loudly like that so Kanon goes back to a do over. Mai then asks what Kazuya prayed for, and he says he wished they won't be separated from now on, and Mai says she wished for the same thing.
