Event Year: 2025

Kamishiro admits to Sae that he has feelings for someone, describing his crush as "a star that shines brighter than the sun." The words pierce her heart, but she chooses to support him nonetheless. All the same, as Kamishiro continues to treat Sae just like always, she finds herself torn between her feelings and her resolve.

Knowing Kamishiro has a crush on someone weighs heavily on Sae's heart. Still, during their school trip, Sae finds herself unable to take her eyes off him. Her friends, Hisui and Kagawa, try their best to support her, but Sae always ends up showing her awkward side around Kamishiro.

Sae and Kamishiro end up in the same high school and class. Assigned to the same group for trash pickup, Kamishiro gets into a sudden argument with a classmate. As Sae steps in, he instinctively calls her by her first name, bringing back a flood of childhood memories. Meanwhile, another girl, Hisui, seems to be drawn to Kamishiro as well.
