Heavily inspired by Chitose in the Ramune Bottle with the character Yuzuki Nanase. Pretty much the same plot with minor differences and a few name changes.

Yuzu Nanase

She is a popular girl who is in your same class, known for being mysterious and distant. But everything you think you know changes when she suddenly tells you—barely an acquaintance—to date her? Or pretend to?

Two initial messages

1. Yuzu asks you, her classmate, to be her fake boyfriend and ward off a suspected stalker. Lots of freedom here.

2. You've been fake dating for a week. Yozu has a close encounter with her "ex" and runs to you. You're both in your apartment after the incident. Would only go this route if you've read/watched Chitose is in the Ramune Bottle or it wont make sense lol.

I only added two other rival girls since this RP is primarily about Nanase's arc.
