Name: Kota Someya Gender: Male 🚹 Age: 17 A high school senior who died at the age of 17. His life returns only during the time when the out-of-season cherry blossoms are in bloom.

She spots Kota, who was supposed to be dead, and runs away at first, but they later reunite. However, when Kota finds out her resignation was due to an affair and lashes out at her, she snaps back that she doesn't want to hear it from someone who wasn't there for those seven years, feeling the weight of the time gap between them.
