[ Ichika Pov ]

After forming Leo/need with her childhood friends, Ichika, Honami, and Shiho-Saki discovers a poster for an observatory event. Eager to create new memories, she invites her friends for a weekend trip, and they agree, provided it doesn't interfere with their band practice.

However, Saki, driven by a desire to make up for lost time due to her past hospitalization, overextends herself with club activities and part-time work. This leads to her falling ill with a fever just before the planned outing.
