Chapter 1

I dated my university girlfriend for four years.

It wasn't until graduation day, the day we broke up, that we finally had our first time.

In the throes of our passion, I couldn't hold back my bitter words.

"What is this, Scarlett? Is this your pitiful compensation for four years of my life?"

Her eyes welled up with tears, and she shook her head frantically.

"You'll marry me, won't you?"

The next day, I was just about to leave with a ring and flowers.

But the police came and took me in.

In the interrogation room:

"Alright, tell us. What was your motive for killing your girlfriend?"

I froze, tears instantly streaming down my face.

I stared at them in disbelief.

"You suspect *me* of murder?"

"I was the one who loved her most in this world, I would have given my life for her! And you suspect me?"

"Look at these flowers and this ring I'm holding! I was going to propose to her today! How could I possibly kill her?"

The more I spoke, the more agitated I became, my interrogation chair shaking as if it would fall apart at any moment.

"What are you yelling about? Do you think we'd arrest you without evidence?"

With that, Captain Miller slammed a stack of evidence onto the table in front of me.

"1. Your girlfriend died in the hotel room you booked. It was a perfect locked-room mystery. No one else entered or exited that room except the two of you."

"2. Your DNA was found inside your girlfriend, your skin tissue under her fingernails, and your fingerprints covered her body."

"3. Her body was covered in bruises and injuries."

"4. Her cause of death was asphyxiation. The towel, used as the murder weapon, was found nearby. It only had your fingerprints and the victim's DNA."

"If you're not the killer, how do you explain all of this?"

"You did such a brutal thing to her, yet you claim to deeply love her? You're a monster!"

Captain Miller lost his composure too, pounding the table and shouting at me.

"I didn't! I didn't!"

Under his aggressive interrogation, my mind was on the verge of collapsing.

"Then why was your phone off the whole time? It only turned back on right before we caught you?"

"My phone battery died. I only realized it when I woke up this morning…"

My body suddenly stiffened.

Holding those files in my hands, as a crime scene investigator myself, I started trembling.

Isn't this a perfect, closed chain of evidence?

With all this undeniable evidence stacked against me.

I was the one who killed my girlfriend!
