Plot[]
It's December 24, the last day to find and solve the big clue. The envelopes contain a Christmas card and a hint. In the courtyard, after noticing the school seal is missing a piece, the girls finally solve the advent puzzle. At the end of the school day, the girls start heading home for a holiday and share their plans for the winter break. But Kanako Miyamae has no idea what she'll do. She wanted to surprise Shizu Shidō. However, she doesn't have anything planned.
Back in the dorm room Mariya Shidō and Shizu are working on the mysterious riddle that came with the advent calendar. Meanwhile, Kanako is talking with her friends when she gets an email from Kirie Onosaka asking her out. This utterly shocks the Kanako and consequently smashes her phone.
Later that evening, the girls are celebrating Christmas. Shizu is planning to go to the chapel but is approaching by an onslaught of girls asking him out. Luckily, Kanako - dressed as Santa Claus - saves him. But before Kanako can ask him, he dashes away.
It's almost midnight when Mariya, Shizu, and the Shinōji twins meet at the chapel. But the doors are closed. Suddenly, Shizu solves the riddle, it's a phone number, which they call. A phone begins to ring, and suddenly the doors fly open. Standing before them is their grandmother. They're happy to see her. But the celebration is short-lived.
Their grandmother is dying. She's lived this long to see if the twin's switcheroo plan worked. Moreover, she has something to tell them before she dies. She wants them to forget about the contest. They can go back to their own lives. They don't have to take over Ame no Kisaki or Mihoshi no Mori. She only wants them to live whatever life suits them.
Mariya walks into her and finds Shizu's gift for her. Her journey to find her one true love has only just begun.
