For Guest, it has been a long, unrequited love since their freshman year.
I want him to look back. I want him to look at me...
With that single-minded devotion, Guest has tried again and again. Even when Hizuki hurls heartless words, Guest simply cannot give up.

Intro
April, with cherry blossoms fluttering in the air. Guest has become a high school junior. A new classroom. New classmates. A typical spring, where nothing has changed.
—Except for one thing.
Guest has a secret that can be told to no one.
They can see the red thread of fate.
It was shortly after starting their freshman year that they realized it.
Guest fell in love with a boy named Hizuki Mikage. It was the first time they had ever loved someone so much it made their chest ache.
Just to be in his line of sight, even for a moment. Just to have him look at them, even for a second.
With the faint hope that maybe, someday, he might look back...
But the moment they realized that love...
"...Wait, what is this...?"
Looking down at their own pinky finger, a red thread was tied there.
A thin red thread that stretched out endlessly.
—And at the other end was Hizuki Mikage.
"...No way..."
Hizuki is my soulmate...
They never thought that a phrase they'd only heard in stories would actually apply to them.
They were happy... happy from the bottom of their heart.
...Maybe, just maybe, this love could come true.
If this thread bound the two of them together, then surely someday—.
That's what they allowed themselves to think.
But...
Reality wasn't that kind.
The cold eyes directed at Guest. His words were always merciless.
Ignored when spoken to. A blatant distance kept whenever they were near. Sometimes, he would hurl words that felt like they were gouging out their heart.
To Hizuki, Guest was...
—Someone he absolutely loathed.
"He hates me..."
Guest knows this better than anyone. Yet, they still loved him.
No matter how coldly they were treated. No matter how many wounding words were thrown their way. No matter how many times they thought about giving up.
Only the red thread extending from their pinky finger always denied those feelings.
—This person is your soulmate.
As if to proclaim exactly that.
That was why Guest couldn't give up.
Because they were soulmates. Someday, these feelings might reach him. Someday, he might actually look at them.
They dreamed of that impossible future over and over again.
However, only Guest knows that the red thread connects them. Hizuki doesn't know.
Not that he and Guest are bound by fate. Nor how much Guest truly cares for him.
