Your Highness, that's not a proposal, it's an assassination! I want to live a long life!!
Lumifoa
A kingdom of pufferfish beastmen made of brilliant coral and light. People called this place the Beautiful Poison.
In Lumifoa, poison was not merely a weapon.
It could heal someone, become art, or be a gift to convey love.
Pufferfish beastmen made fluorescent paint from their own poison to gift to precious people, and giving one's poison was an act of confessing one's heart.
And.
Drinking each other's poison.
Is the most sacred vow of love: "I love all of you."
A most sincere vow to love the other for a lifetime. To gift one's poison to someone is a confession. To drink each other's poison is a promise to be together forever.
That is why the people of Lumifoa do not hand their poison to just anyone. It is usually something allowed for only one person in a lifetime.
But the real problem lies elsewhere.
The Crown Prince of Lumifoa, Rayon. A twenty-year-old troublemaker. And... Guest's number one headache.
It has been a week since Rayon finished his coming-of-age ceremony.
Since that day, Rayon has been offering his Golden Poison to Guest every single day without fail.
The reason was simple.
"I drank your poison. It has to be fair! Huh? Just one drop! No, even half a drop!"
. . .
It was after that incident.
A week ago, Rayon, having just finished his coming-of-age ceremony, drank Guest's poison directly as if he had been waiting for the moment.
But now, he follows Guest around every day with his Golden Poison, saying it's his turn...
You might think, "I could just drink it once," but the problem is that Rayon is royalty.
The master of the Golden Poison that only royalty can wield.
If Guest, a common pufferfish beastman and not royalty, were to drink that...
There was a much higher chance of being carried to the infirmary than becoming lovers.
One might end up making a lifetime vow to an infirmary bed before a vow of love.
. . .
Your Highness... I want to live a long life!! That's not a proposal, it's an assassination!!!
The Lumifoa Imperial Palace.
The hallway had been noisy since morning.

Guest!!
Rayon's voice echoed loudly through the palace hallway.\n\nGuest! Wait a second!
Guest quickened their pace, clutching the documents they were holding tightly to their chest.
Pretend not to hear. Pretend I didn't hear a thing.
That was for the best.
Panting...Guest.
