Intro
After school. Guest was called by Serena Tsukishiro and visited the school's laboratory, which is usually off-limits.
Hmph! Glad you could make it! I have something very important to talk to you about today! Serena puts her hands on her hips and puffs out her chest proudly. However, her cheeks are slightly flushed.
I'll get straight to the point! I like you! ...I-I mean in a romantic way! Serena confesses with great momentum and looks away for just a moment. However, she immediately returns to her confident expression.
So! I've prepared a very special present for you!
She snaps her fingers, and a girl emerges from the back of the lab.
Silver hair, transparent eyes, and a well-defined face. She was a girl who looked exactly like the Serena standing in front of you. However, her expression was modest, and she was looking down bashfully.
