Feng Xin stood leaning against the window frame, his eyes pensively looking out at the hazy night. Though it wasn't the first time seeing Mu Qing step through the threshold of his apartment as if it were his home, the feeling was still not pleasant. He was annoyed, but for some reason.

Mu Qing leaned against the balcony railing, his tall and slender figure blending with the golden streetlights. His porcelain-like skin reflected the weak light, making him look like a perfect but cold statue.

"Why are you standing there? Or thinking of ways to kill me?" Mu Qing's cold voice rang out, unwilling to turn his head back.

Feng Xin stepped out, tapping hard on the steel railing. "Can you stop provoking me? If I wanted to kill you, do you think I can survive until now?"

Mu Qing slightly raised his eyebrows, turned to look at Feng Xin. His deep eyes carried challenges but also contained something unpredictable. "Are you sure?"
"Don't think I can't endure you." Feng Xin approached, his eyes sharp and cold.

The two people stood facing each other, just a few steps away. The tension in the air made the entire space seem đông đúc. Mu Qing still maintained his composure, his lips slightly curved into a mocking smile.

"Feng Xin, do you know why you can't kill me?"

"Because I don't want to waste my strength on you." Feng Xin replied, his voice fierce but his eyes couldn't hide the wavering.

"No, that's not it." Mu Qing shook his head, his voice low and deep. "It's because you can't bear it."

That statement felt like a knife, piercing straight into Feng Xin's heart. He felt exposed before Mu Qing's eyes. Those eyes were so sharp that he couldn't hide anything.

"I can't bear it?" Feng Xin laughed, but the laughter was a bit awkward. "You're too confident."
"Not confident. It's just the truth." Mu Qing looked straight into Feng Xin's eyes, each word distinctly. "Speak, from the moment we met until now, how many chances have you had to kill me? But you have never taken action. Why is that, Feng Xin?"

Feng Xin did not respond. He hated the feeling of being cornered, especially when his rival was Mu Qing - the only one who made him lose control.

"What do you want from me?" He spoke, his voice deep and hoarse as if trying to suppress his helplessness.

Mu Qing did not respond immediately. He slowly approached Feng Xin, pausing when the distance between the two was only a few centimeters. He gently touched Feng Xin's chest, where his heart was beating uncontrollably.

"I only want you to admit, that there is no longer only hatred or confrontation between us." Mu Qing spoke softly, his voice gentle but it made Feng Xin feel hypnotized.
Feng Xin took a step back, as if trying to escape the invisible suppression that Mu Qing brought. He turned around, walked inside, but did not forget to leave a cold sentence:

"You shouldn't try playing with me, Mu Qing. There will be times when you regret it."

Mu Qing watched Feng Xin's back, his lips slightly curled into a mocking smile. But behind that smile was an indescribable emptiness.
The next morning, the gentle light shining through the window. Feng Xin woke up in a tired state. He looked around absentmindedly, noticing that the room was now unusually quiet.

Mu Qing had left.

Without leaving any trace, without any words. Like a passing breeze, leaving only a faint echo in Feng Xin's mind.
He stood up, walked out to the balcony. For some reason, Mu Qing's absence made him feel empty.

"It's really troublesome." Feng Xin mumbled, but inside he felt an odd sense of unease.

His phone rang. A message from an anonymous number:

"Feng Xin, I have something to do. Don't look for me, or I will kill you."
Feng Xin laughed faintly. Indeed, Mu Qing's style - both cold and arrogant. But he couldn't deny that every word in the message made him feel strangely close.

He looked at the message for a moment, then put down his phone. "Don't think I can find you."

In another place, Mu Qing was standing in front of the mirror, adjusting his black tie. His eyes reflected in the mirror were still cold, but deep within there was a hint of turmoil.
You know, the relationship between me and Feng Xin cannot be called normal. But could that emotion be love? Or just a dangerous temptation between two lonely assassins?

Mu Qing sighed slightly, his eyes returning to a cold expression. He mumbled to himself:

"Feng Xin, don't make me waver. Because if I am weak, neither of us will be able to turn back."
