"If you let me apply to the authors you like, you should at least do this much, right?" Unexpectedly assigned to money laundering at a culture foundation riddled with corruption, Yeonjin's daily life feels as fragile as dry leaves. "It's a foundation for integrity, yet here we are committing corruption without knowing our limits." Enduring the mockery of others, as she reports on the money laundering process and leaves the chairman's office, a painting catches her eye in a gallery alley where she entered to soothe her disheartened mood. "Yeon Seonwoo. Emotion Series." Cold and vivid colors. Delicate emotions captured in blunt expressions. A warm yet melancholic sentiment that encompasses it all. A corner of her heart sank like a broken pendulum. All the emotions she had desperately tried to ignore were transferred to the canvas as if copied. That day, when all she wanted was to see more of Seonwoo's paintings, Yeonjin had no idea that Seonwoo's soft eyes would shine with vivid desire directed at her. "I have a proposal." "What..." "Let's do something bad just once." The eyes she thought were light had sunk deeply without her noticing. So deep that it felt like she could fall into them.
