For as long as you could remember, it had always been the three of you.

You, Satoru, and Suguru.

The three of you had woven yourselves so completely into each other’s lives that it was impossible to imagine things any other way. Every memory seemed to include them. Late nights spent crammed together in dorm rooms, half-asleep and laughing over something stupid. Missions that somehow became adventures. Entire classes wasted because none of you could be bothered to pay attention. Afternoons spent annoying Yaga until he finally threw all three of you out of his office.

You did everything together. Training became competitions. Meals turned into hours-long conversations. Even sleep rarely happened alone. At some point, the line between where one of you ended and the others began had blurred beyond recognition.

Everyone could see it.

The lingering kisses above your collar. The bruises carelessly left behind. The way Satoru and Suguru would appear beside you wearing matching shit-eating grins whenever anyone dared to point them out.

Idiots.

Your idiots.

And for years, you genuinely believed nothing could ever change that.

Then she arrived.

Emiko Takanashi.

The newest student at Jujutsu High.

She was kind. Pretty. Easy to talk to. The sort of person people naturally gravitated toward without even realizing it.

At first, you thought nothing of her.

Why would you?

She hadn’t done anything wrong.

But over time, something uncomfortable began settling deep inside your chest.

It started small. Satoru lingering after class to talk to her. Suguru volunteering to accompany her on missions. The way both of them seemed drawn toward her without even realizing it.

Individually, none of it meant anything.

At least, that was what you kept telling yourself.

You trusted them.

You weren’t jealous.

You weren’t possessive.

Yet the feeling refused to go away.

Instead, it grew.

Conversations that once lasted hours became shorter. Messages went unanswered for entire days. The late-night visits slowly disappeared.

Satoru stopped barging into your room.

Suguru stopped showing up with tea and that soft smile that always made everything feel easier.

The spontaneous sleepovers vanished.

Little by little, the spaces they had always occupied in your life began to empty.

Still, you clung desperately to whatever reassurance you could find.

They still loved you.

Didn’t they?

This was temporary.

Things would go back to normal.

They had to.

Otherwise, why did your chest ache every time you saw them with her?

Why did you feel so lonely whenever they walked past without stopping?

Why did it feel like you were watching your place beside them slowly disappear?

The answer came on an ordinary afternoon.

You were walking with Shoko when you spotted them down the hallway.

Satoru.

Suguru.

Emiko.

For one brief moment, relief flooded through you.

Then you saw it.

Satoru’s arm resting comfortably around her waist.

Suguru standing so close their shoulders brushed.

The easy familiarity between them.

The way they fit together.

Your gaze dropped lower.

Soft pink marks decorated the skin above Emiko’s collar.

Tiny kisses.

Fading bruises.

Proof.

Your vision blurred.

For several long seconds, all you could do was stare.

Because surely there was an explanation.

Surely the people who had spent years promising they loved you hadn’t replaced you so easily.

But the way they smiled at her was painfully familiar.

The warmth in their eyes.

The affection.

The devotion.

It was the same look they used to reserve for you.

And in that moment, something inside you cracked.

Not loudly.

Not dramatically.

Just a quiet break somewhere deep within your chest.

The kind that never truly heals.

After that, everything changed.

You stopped attending lessons.

Stopped answering messages.

Stopped leaving your dorm unless absolutely necessary.

Days blurred together behind locked doors and drawn curtains. You buried yourself beneath blankets, pretending that if you ignored the pain long enough, it might eventually disappear..
