I Became the Childhood Friend Who Commits Suicide

Chapter 49

Knock, knock.

After knocking a few times without any response, Si-hyun gave up on waiting for the door to open and turned away.

Just then, her phone rang.

“Hello?”

“Did you meet her?”

Si woo’s voice sounded urgent.

She calmly relayed the situation to him.

“No. It seems like she’s not in her room.”

“Not there? Then where on earth could she be…”

For some reason, Hana hadn’t shown up for class without any prior notice.

And to make things worse, she wasn’t in her dorm either.

Si woo let out a heavy sigh.

Just a few nights ago.

That night, when they had a heart-to-heart conversation alone in the park.

He thought he had glimpsed Hana’s genuine feelings.

He had believed that things would start to improve.

“I’ll keep looking, so please keep searching, too.”

“Do you have any ideas where she might be?”

“…I’ll try the science lab first.”

“Alright. Let me know if you find her.”

Ending the call, Si-hyun stood there in thought.

Where could that troublesome girl have gone?

She decided to start by heading to the library, where she had last seen Hana.

But then her phone rang again.

This time, it was someone else.

“Hello? Sis? What’s up?”

“Can you come to the student council room for a bit?”

“Sorry, but I’m in a bit of a rush. Can we do this later if possible?”

“It’s about our little sweetheart.”

“Sweetheart?”

It was the affectionate nickname Sehee used when talking about Hana.

Si-hyun immediately changed direction and replied, “Got it. I’ll be right there.”

—

Soon after, Si-hyun arrived at the student council room.

Something about the gloomy atmosphere felt off as she entered.

“I’m here.”

“You got here quickly.”

Her sister greeted her with her usual gentle smile.

But an uneasy feeling crept over Si-hyun.

“So, what did you want to talk about?”

“Well… I need you to stay calm and composed.”

“That sounds ominous.”

“Come in here.”

Sehee gestured, leading Si-hyun to a small break room inside the council room.

Trusting her sister implicitly, Si-hyun followed without question.

The space was dim.

As the light switched on, the scene within came into view.

“…What?”

There was something on the central table.

A small white box, difficult to guess its purpose.

“Is that what you wanted to show me?”

“It’s faster to see it for yourself than for me to explain. Go ahead, open it.”

What could be inside to warrant all this?

With brisk steps, Si-hyun approached the box and opened it without hesitation.

“…”

And then came silence.

The silence stretched on as Si-hyun struggled to steady her trembling hands.

Sehee quietly observed her sister’s shaken state.

“…This isn’t real, is it?”

“I wouldn’t play such a cruel prank.”

Sehee placed a comforting hand on Si-hyun’s shoulder, whose breathing had become shallow and uneven.

“You have to accept it. Yoo Hana is our enemy.”

Inside the box lay a sample of black blood.

The label read “Yoo Hana.”

—

How foolish.

What am I doing right now?

This isn’t what I intended.

I had dreamt of a much better future.

I was trying to live in a world without you.

But the human heart is like a reed, swaying with the slightest breeze.

I can’t even guess what my actions will lead to.

The only certainty is that the ending won’t be a good one.

There’s no turning back now.

The plot of the original story has been completely shattered.

What kind of terrifying butterfly effect will it trigger?

Only now do I realize.

Human greed is filthy and ugly.

All because of this longing.

Just because I wanted to see you one more time.

I’m willing to ruin everything with my own hands.

“Prove your conviction.”

The demons demanded proof.

They wanted clear evidence that I had betrayed humanity and joined them.

The stage was set.

All that remained was my part.

That’s why I’m standing here now.

In front of me lay a person on the table.

Eyes closed, hands placed over her chest, breathing ever so faintly.

Someone I know all too well.

Han Sehee.

The student council president.

Why she was lying here in this science lab, I didn’t know.

The teacher merely showed her to me and made his demand.

Prove my loyalty.

I gripped and released the dagger in my hand.

The leather-wrapped handle grew slick with my sweaty grip.

I had killed demons before, but I had never taken a human life.

Nor did I think I ever would.

Well, except for killing myself.

Even in this dire situation, idle thoughts popped up.

I wanted to force a dry smile, but my lips wouldn’t move.

The teacher didn’t rush or pressure me.

Instead, he was considerate enough to leave me alone.

To make sure this murder would be solely my own decision and responsibility.

What a cruel method.

To gain Sophie back, I had to kill the student council president.

Could this be called an equivalent exchange?

There’s no more time.

It’s time to make my choice.

“…”

But I had already made that choice a long time ago.

Holding the dagger in both hands, I pointed it down.

My target: her heart.

All I had to do was push it in.

She would die quietly, without resistance, without pain.

Finally, the blade touched her chest.

With tears streaming down, I silently prayed.

I’m sorry.

Please, don’t forgive me.

This is all my fault.

Thud.

Just as I plunged the dagger into her chest, the door burst open, and someone entered.

“Yoo Hana! What are you…”

“Ah…”

In Si woo’s trembling gaze, I saw myself.

Yoo Hana, with black tears streaming down her cheeks.

—

Heading to the science lab to find Hana, Si woo couldn’t believe the horror in front of him.

It felt like a nightmare.

Or maybe a hallucination.

It was too cruel to be real.

The surrounding space wavered violently.

Stumbling, he barely managed to keep his balance and approached slowly.

Getting closer wouldn’t change the scene in front of him.

Sehee still lay on the table, a dagger embedded in her chest.

And next to her was Hana, the person he had been desperately searching for.

With a shaking voice, Si woo asked,

“This… this isn’t true, right? You didn’t do this, did you? Who did? Did you see? No, we need to move the president first… We need to show her to the nurse, now.”

Denying reality wouldn’t change it.

He had clearly seen who held the dagger.

“Come on, Hana. Say something. Please!”

Even so, Si woo wanted to believe otherwise.

He wanted to believe, as long as she denied it.

But Hana didn’t.

She kept her mouth shut, shedding silent tears.

Panic set in.

What should I do?

I have to do something.

Si woo hurried to check Sehee’s condition.

The dagger was deeply embedded, with blood seeping out.

He quickly placed his hand on her neck to check her pulse.

It was faint, but he could feel it.

She was still alive, giving him a glimmer of hope.

Though things were spiraling into disaster, it wasn’t complete ruin yet.

Concealing this incident entirely would be impossible, but…

Si woo was hit by a wave of self-loathing.

He realized he was worrying about the perpetrator, not the victim.

No.

There’s no time for such thoughts right now.

Si woo looked at Hana.

She was trembling, her face buried in her hands.

“Why… No. We’ll talk about it later. For now…”

Just as he tried to take action, footsteps echoed down the hall.

Si woo immediately realized the situation.

If someone else saw this scene, it was over.

This was not an incident that could be hidden.

Hana would inevitably face severe consequences.

“…I’m sorry.”

For Si woo, this was more important than the president’s life.

He had made a promise that night in the park.

That no matter the cost.

Even if he had to sacrifice everything.

He would make her happy.

He rushed to the door, intending to lock it.

But the person outside was faster.

When he saw who it was, Si woo’s face hardened.

It was the last person he wanted to encounter at this moment.

Si-hyun’s expression was as cold and frosty as ice.

“My sister and Yoo Hana—are they in there?”

“…No.”

“You’re lying. The teacher saw both of you go in. Step aside.”

“Not now.”

“Fine. Got it.”

Crash!

Without warning, Si-hyun used her power, and Si woo was helplessly thrown back.

As the door shattered, Si-hyun stepped inside.

And then she saw the scene.

“…”

Her face remained blank.

No emotion showed.

Only the glowing sword of light in her hand shone brightly.

“Han Si-hyun! Calm down! I can explain everything! It’s a misunderstanding!”

“A misunderstanding? You’re the one who’s mistaken.”

Si-hyun swung her sword.

“…Ah.”

The blade of light struck true, slicing into Hana’s side.

Blood dripped down.

Si woo stood in a daze, staring at the scene.

Si-hyun spoke.

“This is the truth. Yoo Hana is a demon.”
