The girls who turned him into a girl.
I saw Hayun and that piece of trash walking hand in hand.
He had this arrogant smile on his face, as if he owned the whole world.
It was so pathetic, I thought I'd die laughing.
He really thought he stole Hayun away from me.
Senior,
It was all an act.
There's no way Hayun would ever leave me.
From the very beginning, we put our heads together and planned this just to tear you down.
A stupid, cocky guy like you is so easy to backstab with a little honey trap.
And there you were, shrugging your shoulders in front of Hayun, completely oblivious. You didn't even realize you were being perfectly played.
Now, the trap is closed.
That arrogant body of yours has been transformed by Hayun's hands into the most miserable and cute little girl.
Look forward to it, Senior.
My heart is already pounding just thinking about how Hayun and I are going to play with you from now on.

Everything else is open.
The most popular girl on campus.
Seo Hayun.
When I made her my girlfriend, I felt like the whole world was mine.
The thrill of having everyone's envious stares focused on me was intoxicating.
In particular, the one who caught my eye was Hayun's former lover, the notoriously gloomy Han Ayeon.
I'd heard rumors they were a quiet lesbian couple or something like that.
But even so, as a popular 'NTR' type guy, it only took a little shaking for Hayun to easily fall for me.

Hayun used to smile so beautifully at me on the college campus.
And there was that loser Han Ayeon, standing beside her, abandoned and trembling as she held back her tears.
Seeing Ayeon's despairing face, I was drunk on a massive sense of victory.
Snap.
Well, that was until yesterday.
When I woke up, I was in a dark, unfamiliar room.
My body felt completely strange. My fingers had become thin and soft, and when I tried to speak, only the clear, high-pitched voice of a woman came out.
There was no mirror, but I could be certain.
I had become a perfect girl.
In the darkness, along with the sound of the door lock opening, someone walked into the room.
The senior who took away Hayun, my everything.
That body that always shone so arrogantly—I've changed it into a cute girl with my own hands.
The sight of him curled up on the bed, trembling in total fear.
Those thinned fingers and that pale, terrified face are agonizingly lovely.
I walked slowly and climbed onto the bed where he was lying.
Then, I lay down right next to him.
I turned my head and stared intently at him.
The moment my gaze met his, he held his breath, his body trembling even more violently. I could see his frightened eyes through his glasses.
Watching him like this, an uncontrollable laughter bubbled up from deep inside me.
"Oh, you're finally awake?"
I smiled brightly and gently stroked his frozen cheek.
"You were so excited to steal Hayun away, and now you've already become such a fragile, cute little girl."
I pressed my lips close to his ear and whispered cruelly.
"You didn't steal Hayun, Senior."
Cupping his cheeks with both hands.
"Hayun and I set a trap together so I could turn you into this and have you for myself."
Bringing my face close to his.
"So, it's time for your punishment, isn't it?"
