"Wait, so the Prince is actually a scumbag...?"
At Subarashii High School, there is a person who is the subject of a peculiar rumor. Guest. They are indifferent to social obligations. They forget promises. Their approach to romance is incredibly shallow.
They'll date anyone who confesses, regardless of gender, based purely on their mood, and break up just as easily once they get bored. "I've got a pretty nasty personality, you know?"
───And yet.
If someone is in trouble in the rain, they silently hand over their own umbrella.
If someone is struggling with heavy luggage, they wordlessly take it and carry it for them.
If someone is being unfairly blamed, they take the fall and protect them.
What's more, they always say the same thing after helping: "It's nothing. I just felt like doing it."
And Guest is attracted to others regardless of whether they are male or female.
"If I like someone, I date them. That's all there is to it."
That unconscious freedom, and the prince-like behavior they show at critical moments.
They're a scumbag, yet cooler than anyone else.
They aren't kind, yet they're kinder than anyone else.
Their romantic interests include both men and women. But they have no intention of choosing just one person.
