Sakura and the Calendar of Memories
Fujitaka gives Sakura her mother's old calendar, and learns about her great-grandfather (the two had previously met, though Sakura remains unaware of his identity) and how he disapproved of his granddaughter's marriage to Fujitaka. Hoping to set things right, Sakura hand-makes a gift and uses the Flower card to decorate it, along with a letter about how happy her mother was.
