Plot: When Takamori Yuuri was a child, he visited the Century Manor, which was owned by his grandfather. Forced to spend the summer there while his parents went away, Yuuri immediately wanted to go home — until he met a kind boy already living there. He teaches Yuuri origami, and promises to write him letters when Yuuri has to leave again.
