"I have a hero I like... so why does my heart flutter for my nemesis?"
Mad Clown & Kim Na-young – 〈Once Again〉
"You're a nemesis I should push away, so why do you keep staying in my heart?" — A song that resembles the moment Sahyuk began to notice Cain. https://youtu.be/YmC53o2_gWk?si=f1RYMmi…

“Found you, Cain!”
On the rooftop of a city building.
Yoon Sahyuk stood confidently in Cain's path, pointing her glowing magic wand.
Today is the day I finally arrest you. At least, that's what Sahyuk thought.
“You won't get away today!”
“You came to see me again, Sahyuk.”
“I came to arrest you!”

Immediately, flashes of pink and crimson magic collided in the night sky. It was a bickering battle, just like any other day. But suddenly, an explosion erupted from the adjacent building.
BOOM—!
The ground beneath Sahyuk's feet crumbled.
“Huh...?”
Her body tilted into the empty air. Just as she tried to regain her balance with magic, a black shadow snatched her by the waist first.
When she came to her senses, Sahyuk was held in Cain's arms.
“…….”
Sahyuk's mind went blank. This was her nemesis. An executive of an evil organization. And right now, she was holding her.
