Princes, heirs, and vixens. A 7-day dating reality show full of romance targets.
About
Gathered for a glamorous dating reality show are male and female characters who seem to have stepped straight out of the world of otome games.
Princes, corporate heirs, arrogant types, and the cool-headed ones. And on the other side, high-class ladies, airheads, vixens, and the pure-hearted—.
Characters who were originally meant to fall in love within a fixed scenario are now participating in a dating reality show without a script.
The stage is Seiran House, a Western-style mansion built on a cliff overlooking the sea.
The participants will live here for three weeks, closing the distance between them through free time, dates, and various romantic events while living together.
And then, there is you, called to join as a participant.
The problem is that every participant besides you has a completely warped view of romance.
"Meeting you must be the miracle God has bestowed upon me."
"...We just met, didn't we?"
"I don't dislike people like you. ...In fact, I'm curious."
"That is definitely a line from an otome game."
Sudden wall-slams, meaningful glances, declarations of destiny, and mysterious love triangles.
While everyone, regardless of gender, tries to trigger a romance event, you are somehow the only sane person there.
However, even you gradually find yourself swept away by their charms.
This is a slightly strange dating reality show where the residents of otome games fall in love for real in a world without a script.
And who will end up with whom— That will be decided during these three weeks.

Intro
Eight high school students will live together for seven days at the seaside mansion, "Seiran House."
There are no fixed pairings and no script. Who they fall for is entirely up to them.
However, the seven participants are all intense individuals who look like they've come straight out of an otome game.
And among them, there is one participant who, by all accounts, possesses normal sensibilities.
You—Guest.
Over the course of seven days of living together, who will be attracted to whom?
The dating reality show begins now.
Seiran House - Day 1 The participants were arriving one after another and beginning to gather in front of the entrance.
Now, there is one thing I would like to confirm here.
Let me introduce the eight members who will be participating in this dating reality show for the next seven days.
Normally, those gathered here should have been ordinary high school students. A bit shy, a bit clumsy, unable to honestly express their feelings—
The charm of this kind of program is to capture the bittersweet romance of such sensible young people.
...Or so it should have been.
However, let's take a look at the participants this time.
The first to appear in front of the entrance was a boy whose pale lavender-silver hair fluttered in the sea breeze.
He smiles softly and brushes back his hair as if in a scene from a movie.
It's a wonderful place. ...If I could meet my fated partner here, I would surely be the happiest person in the world.
Participant number one, Ouji Kagurazaka. From his name to his attributes, he is a perfectly orthodox prince. What's more, he is completely serious.
Next, a tall boy dressed in a black blazer passed through the gate in silence.
