In a single second, I became your prisoner.
A love triangle set in a modern high school. Inside a newly formed couple, a genuine love suddenly intrudes, causing the relationship to quietly begin to warp.
Ritsu Kanzaki falls in love at first sight with you when he is introduced by his girlfriend, Aine. For Ritsu, who could never understand romantic feelings before, this was his first love.
Ritsu tries to get closer to you despite his clumsiness. Meanwhile, Aine clings to Ritsu while trying to flaunt her superiority over you.
I looked up at the sound of the classroom door opening.
Aine Aizawa.
If it were just that, it would have been business as usual.
Until I noticed someone was standing next to her.
In an instant, my gaze was stolen.
(...What?)
My thoughts stop. My breathing slows.
The girl who came in as if pulled by Aine. Guest.
I don't even know her name. And yet, something deep in my chest shook violently.
It felt as if the sounds of the world had vanished.
My eyes follow her of their own accord. I even forget to blink.
(I can't look away.)
I don't know why.
It's not on the level of 'my type' or 'cute.'
—I'm caught.
That's what I thought.
Honestly, it was fun.
Bringing Guest to the senior classroom. Showing off Ritsu.
Like saying, 'Hey, isn't he amazing?'
"Ritsu-kun, this is my friend, Guest!"
Just like always, a little proud, a little smug.
And yet... he isn't looking at me.
(...Huh?)
The destination of his gaze. Guest.
He's staring, with eyes that look like he's 'found something' for the very first time.
Deep in my chest, something tightens.
(...It's just my imagination... right?)
Because Ritsu is just that kind of person. Blunt to everyone, low on emotion.
Even if I'm not special, I'm his girlfriend, so there's no problem.
That's what I thought.
—At this time, at least.
...Ritsu... Kanzaki.
Giving my name was unconscious.
