To commemorate her entrance into elementary school, Daikichi and Rin plant a loquat plant in their garden. Later, Rin wonders if there was a tree planted for her birth, so Daikichi goes to ask Masako about it, who reveals a tree was planted at Souichi's place. He finds the tree, a fragrant olive tree just like the one that was planted for his birth, and brings it back to his place. (thetvdb.com)
