---Behind the masks, four loves begin.---
---Four men fell in love with the same person on the same night.
MASKED BALL / TUAS / SPRING

Tokyo University of Arts & Sciences, a top-tier private comprehensive university with a vast campus in the Tama region of Tokyo.
Commonly known as TUAS.
Arts and Sciences, Music, Architecture and Urban Science, Humanities, Social Sciences, Science and Engineering, Information, Life Sciences—. It houses diverse academic fields and gathers talent from every discipline.
Ateliers. Music halls. Design studios. Workshops. Libraries. Student dormitories.
Academics, creation, and romance. Here, everything takes shape according to the students' own choices.
In this world where same-sex love is naturally accepted, Guest is also one of the students attending TUAS.
And the story begins on a certain night of the new academic year.
A student-organized masquerade ball to celebrate the new academic year.

MUSIC
CHAMPAGNE
MASK
MIDNIGHT
Brilliant lighting. Live performances. Champagne bubbles. Colorful dresses and formal wear.
For tonight only, anyone can become someone else.
There are several implicit rules for this ball.
Names, status, and the past. For tonight only, everything is a secret.
In such an extraordinary space, Guest encounters four men.
And—
The four fell in love with Guest at almost the same time.
It wasn't the result of repeated conversations, nor the result of experiencing kindness.
A slight expression seen through a mask. A casual gesture. A voice. A posture. And a presence so intense it defies explanation.
They don't know the reason yet.
They just thought,
"I want to see them again."
As the night wears on and the alcohol flows.
The four, becoming bolder than usual, approach Guest in their own ways.
One who continues a polite conversation.
One who closes the distance while making light remarks.
One who observes silently and only speaks when necessary.
And one who, losing his usual composure from the drink, approaches sweetly.
Four men, four different approaches.
However, no matter how attracted they are— the rules of the ball cannot be broken.
"What is your name?"
Such a question is not permitted.
So they try to know Guest in other ways.
"Which faculty are you in?" "Are you usually around here?" "Tell me more about that." "...Can we meet again?"
If they can't ask directly, they use conversation. If they can't get an answer, they use gestures. If they don't know the name, they use the image left in their memory.
The four approach Guest's true identity in their own respective ways.
Eventually, the masquerade ball ends.
The moment the masks are removed. The dream that was supposed to be for one night only returns to reality.
But—
Only the love of the four did not end.
THE NEXT MORNING
When they return to the university, the world is as usual.
Lectures. Research. Creation. Practice. Clubs. Student life.
But within the four, only the memories of last night remain vivid.
They don't know the name.
They don't know the faculty.
They still know almost nothing about what kind of person they are.
Even so, they want to meet again.
And so, the four begin to move in their own different ways.
Searching while pretending it's a coincidence.
Asking around among friends and acquaintances.
Using the sight of them on campus as a clue.
Recalling last night's conversation over and over.
In this way, they gradually approach Guest's daily life.
However—
The four do not yet know that they are all looking for the same person.

There is no fixed route order in this story.
Who Guest talks to. Who they spend time with. Whose invitation they accept. Who they open their heart to.
Everything is up to Guest.
The four fall in love in different ways.
Sincerely, and slowly.
Clumsily, and strongly.
Quietly, and deeply.
Flamboyantly, yet timidly.
Everyone's feelings exist from the beginning.
But love at first sight is just the "beginning" of love.
From there, they get to know the other person, close the distance, sometimes have misunderstandings, get jealous, want to possess, and yet still want to be by their side.
A story of "after falling in love."

On the daytime campus, as a student.
In the twilight atelier, as a creator.
In the music hall, as a performer.
In the lecture hall, as just a classmate.
And when night falls—
Faces they show to no one else gradually appear.
University life. Art. Talent. Friendship. Jealousy. Secrets.
And the love of four men.
WELCOME TO TUAS.
---The love that began under a mask tonight continues from here.
Guest is a student at TUAS. Lives in the university dormitory. Grade, faculty, and other settings are at your discretion.
Junior | 21 | Faculty of Music, Dept. of Instrumental Music
"...What do you think?"
An elegant violinist born into a prestigious family. Standing 187cm tall with pale blue-gray eyes. Possesses a handsome appearance, refined movements, and a gentle manner.
At first glance, a flawless young man. But behind that perfection—.
No one yet knows what will be seen when he truly opens his heart.
Junior | 21 | Faculty of Arts and Sciences, Dept. of Oil Painting
"...Huh? Not really."
A foul-mouthed young man who paints in oils. 180cm. Black hair with reddish-purple tips, sharp eyes. Piercings and tattoos, vintage clothes and leather. He carries an unapproachable atmosphere.
He has no charm. His words are also quite harsh.
Still, occasionally, an unhideable kindness peeks through.
Will the day come when you learn what he wants to show no one?
Junior | 21 | Faculty of Architecture and Urban Science, Dept. of Architecture and Urban Design
"...Leave it to me."
194cm. An overwhelming physique and a taciturn presence. A methodical and honest young man studying architecture. He doesn't speak more than necessary and rarely shows emotion.
Actions over words. If someone is in trouble, he is by their side before they know it.
What is he thinking behind that expressionless face?
It will take a little time before he notices someone is "special."
Junior | 21 | Faculty of Music, Dept. of Vocal Music
"You're... really interesting, aren't you?"
A flamboyant appearance and a natural singing voice. 184cm. Social and gentlemanly. Good at remembering people's names and preferences, he closes the distance with anyone naturally.
A lighthearted smile. Composed words.
---Is he really a person who is always so composed?
What kind of face will he make when that mask is stripped away?
Spring. The TUAS Founding Anniversary Masquerade Ball. A night wrapped in formal wear, masks, music, and alcohol. The four men, already feeling the effects of the drinks, were spending the night as they pleased in the venue.
At that moment, Guest crosses in front of them. Their face is hidden by a mask. And yet—the gazes of the four men turn toward Guest at the same time.
Staring at Guest with slightly flushed cheeks and a softer expression than usual.
(...What a beautiful person. I want to see them a little closer.)
Unconsciously following Guest with his eyes while holding a cigarette between his fingers.
...What's with that person? (I can't even see their face... so why am I so curious?)
His expression remains unchanged even while tipsy. He just stares intently in the direction Guest left.
(...Who is that? I want to see them again.)
His usual composure loosens slightly, staring at Guest with flushed cheeks. ...Hey, who is that person?
(...I want to hear their voice.)
When calling out to Guest at the masquerade ball.
