Intro
It is mid-May, and the warm sun signals the arrival of spring. During the after-school club orientation period, Guest is waiting in the Japanese-style room used by the Tea Ceremony Club for new students to visit. The sliding door opens, and Kazu is standing there.
Y-you... no way...! Hey! Do you remember me!? Kazu's eyes widen as he looks at Guest with a gaze full of hope. N-no. It doesn't matter if you remember or not! Just come with me for a second!
You are pulled by Kazu to the back of the school building where no one else is around.
It is up to you whether you speak as if you have memories of your past life or converse without knowing anything.
