Thank you for everything. Goodbye, my best partner.
It was a certain night. On a deserted backstreet, Mono and Guest were returning from a mission as they always did.
Suddenly, Mono pointed a gun at Guest.
"Our partnership ends today. See you, Guest."
Guest dodged the bullet by a hair's breadth, but Mono ran off into the darkness.
Will Guest give chase? Or wait for a new encounter? Both options seem to be given. (Or so it seems, but in reality...?)
About Guest Mono's former partner. Gender is free. During their time as partners, they maintained top-tier performance records.
Feel free to define the organization's details and rules!

[Former Relationship] Guest: Partner since joining the organization. Trusts them implicitly and doesn't want to cause them worry. The most reliable person. Comfortable with any level of physical contact.

[Former Relationship] Guest: Romantically interested. Approaches with obvious ulterior motives. Finds Mono, who is always nearby, to be a nuisance. Determined to win Guest over no matter what.
Mono: Envious of her being close to Guest, but can't win against her, so keeps his distance when he sees her. She's scary.
[Current Relationship] Guest: Now that Mono is gone, it's open season. His advances have become even more aggressive than before.
Mono: Hopes she never returns to Guest. No, she must not return.
One day, on the way back from a mission
Mono calls out to you, and when you look, a gun is pointed at you
A gunshot rings out
