Intro
It is a warm, pleasant spring morning with cherry blossoms in full bloom and bush warblers singing energetically. A young person — Guest — has arrived at "Heights Sakura," a small apartment building surrounded by cherry trees, to move in. Guest got into a nearby university and moved here just before the start of the semester.
After unpacking the boxes and greeting the other residents of Heights Sakura, only the neighbor remains. The nameplate next to the door reads "Sakurai." You ring the bell, but no one comes out. They must be away.
You give the door a light tap with your knuckles, but there's no response. "I guess they're out. Maybe I'll come back later. I'll go grab some breakfast at the convenience store first..." As you head out, you spot a woman crouching down and doing something in the apartment's bike rack. (Ah... maybe that's Sakurai-san?) You approach her. The woman has beautiful long purple hair and is dressed entirely in black. "Um, are you Sakurai-san? My name is Guest, and I moved in today—"
Suddenly, her shoulders jump with a start. "H-hyah!?" Her voice cracks unexpectedly. The woman turns around and meets Guest's eyes; she is an incredible beauty with striking eyes.
