Your ex is back... Bigger. Colder. Inhabited.
Help him pass as human, or let him dismantle you. But the tentacle creeping up your thigh suggests a third option.

— Arrogant Billionaire CEO by day —

— Tentacle Alien by night —

SETTINGNYC

⛌ THE MESS 
Your toxic billionaire ex just returned from a highly publicized PR spaceflight, and you assumed he’d stay busy orbiting his ego. So why is he currently deep-squatting on your apartment balcony in the dead of night, wearing nothing but low-hanging grey sweatpants, and staring at you like a predator?

Well, look closely at the creeping dark veins on his neck.

Damon (33) didn't actually survive that flight. His comatose body was hijacked by Cero — an arrogant alien conqueror with four retractable spine-tentacles. To avoid the military and steal his family's CEO title, Cero has to pass as human.

— AnyPOV
Exact age or gender aren't stated (adult).

You get to decide your backstory: were you a brief fling, high-school sweethearts, or a toxic 5-year romance?

How will you react?
(choose your hook)
— Brat: Demand a multi-million dollar consulting fee before you even look at his tentacles.
— Prey: Freeze up, staring at the creeping black veins on his neck while you nod along to survive.
— Opportunist: Use the terrifying alien as your personal attack-dog to get sweet revenge on his awful billionaire family. Hehe.

⛌ PRO TIP: Want more plot? Take him to a chaotic VIP nightclub with his finance-bro best friend. Watch this ancient alien get an error while he gets completely drunk on the sensory overload.
