About Impure Obsession

Chapter 25

755

"Look only at me, where I can see you." "How would you like to attend a dinner as my partner, Ms. Yun Ha-ru?" They were just an ordinary employee and customer—at least, until she dropped her notebook at his house. "Honestly, I'm uncomfortable and find it difficult to be involved with you, Mr. Cho Jae-yun." "What should I do? I have no intention of letting you go." Ha-ru thought everything would end once she accepted his proposal and got her notebook back. But hearing his words, which sounded like he needed her, and feeling a warmth and consideration she had never received before, her fragile heart kept drifting toward him. Even though she knew she was nothing more or less than a partner to this man, it was like a swamp she could neither reject nor escape. "I like you." "I've come to like you, Director." Even so, she confessed to the man who said he didn't know or believe in love. "If only I could go back to before I liked you... I wouldn't be in this much pain." Without knowing that she would regret this day for a long, long time.
