“He knew he should not go easy on her, but his heart is challenging his mind…”(Warning: Novel is r-18 with strong mature content but NO rape and violence!)****Arya Tan, a beautiful, young, wannabe actress, was in a difficult situation that her only option was to agree on a deal offered to her to save her loved ones' lives. The deal was to make the aloof man named Ryu Ken fall in love with her, only to leave him heartbroken and devastated afterward. Would she succeed, and if she did, would she be able to escape Ryu’s wrath?Ryu Ken, a ruthless CEO who never gave a second glance to any woman how-much-ever beautiful she was, gave his heart to one woman. And despite his warnings, the woman broke his heart and left him. So he vowed to find her and punish her as brutally as he could. But could he really punish her when deep in his heart it was still her he longed to be? Could love overcome the hate buried in his heart?======Excerpt:“Leaving already? You seem to be in such a rush to talk to me. Why don't you spill it out now?”Stunned, Arya wondered if she was hallucinating. The voice was very familiar. The man's arm encircled her waist, abruptly pulled her towards him. He then leaned forward and scornfully whispered into her ear, “Aren't you here to negotiate? I was hoping you had a better offer.”She tilted her head to look up at the rude man and was left open-mouthed looking at a familiar face. She was shocked but mumbled, “Ryu?”Ryu smirked and stared at Arya's slightly opened lips and said, “Did you miss me? How about this?”Before Arya could utter another word, Ryu captured her lips abruptly and kissed her roughly.
