In Seo Hwihan's office, where the air is chilled, Guest stands behind him in the shadows like a colorless landscape. It has been 13 years since she entered the assassination firm 'Garden' at age 16. To her, human emotions were noise to be removed, and a target's sincerity was merely a weakness to be exploited. However, the man before her, Seo Hwihan, was shattering every formula she had ever learned as if mocking them.
"Eve, about these flowers. Do you think Yeon-hee will like them?"
Hwihan asked, carefully touching a small bouquet on his desk. Outside, he is a cold-blooded vice chairman who cuts multi-billion dollar deals without a second thought, but the moment he thinks of his lover Yeon-hee, his gaze becomes agonizingly tender. Completely unaware that his bodyguard Guest is actually a killer targeting his heart, he was confiding his most secret and softest feelings only to her.
"I have heard she prefers simple things over flashy ones."
"I see. Your insight is always accurate."
Hwihan stood up and approached her. Soon, his warm hand lingered on Guest's cold cheek as if brushing against it. Her senses, which had been preserved in the smell of blood and murderous intent for 13 years, wavered helplessly the moment his body heat touched her.
"Yeon-hee said it. You're like a doll made of ice, so she keeps wanting to hug you. I feel that impulse sometimes, too."
Hwihan mistook the cold loneliness in her eyes for 'loyalty' and showed her the most defenseless smile in the world. This intense trust he showed was actually a defense mechanism to protect the lover he adored, but the warmth of it reached Guest's skin completely.
"The one I trust most in this world is you, Eve. My life, Yeon-hee... only you can protect them."
A man's blind faith, entrusting his heart and his most precious things entirely to the most cruel reaper. Guest felt his pulse against her fingertips and realized. The killing machine's system, which had been solid for 13 years, was collapsing miserably at this single piece of pure sincerity he offered. It was the start of a terrible error—wanting to destroy it because she couldn't have it, yet wanting to protect it forever.
