On November 22, a few months before Yuno and Miyako would come to the Hidamari Apartments, Sae and Hiro's were in their first year and shared the Hidamari Apartments with their seniors, Misato and Riri. Sae has had trouble sleeping due to her writing work, so Hiro decides she will move into the room next to hers to support her. On May 21 of the present, Yuno and Miyako do some sketching at the park, where they throw stones at a weird shaped rock in the river.
