S1·E16 Sakura and the Rainbow of Memories

Sakura's family and Yukito takes a vacation to the country side. Sakura meets the old owner of a country mansion near their rented cottage. He invites her over for tea, tennis, and they become good friends. He shows her the room of his granddaughter, now deceased, and gives Sakura clothes that once belonged to her. The next day, Fujitaka gives Sakura cookies to give to the old man. When she brings them out to eat, the old man asks her about her father. On the last day of her vacation, Sakura asks the old man to stand in the balcony of his granddaughter's room. From a distance, Sakura uses the Rain card to give the old man a rainbow as a goodbye gift. Sonomi comes out of hiding to speak with the old man to reveal the old man is the grandfather of both Sonomi and Nadeshiko, and Sakura's great grandfather.
