My obsession: The CEO

Ana Smith knows that she is different from others since her childhood. She is not a genius like her sister, but she has this dark side of her that breaks out sometimes, and disaster happens after that, hence she was always asked to stay in the shadows, and so she did. But then at the age of 25, she was killed in a fire along with her grandpa. Not knowing who killed her made her soul restless, the agony of losing the only person she was capable of loving, she prayed hard to god for a miracle, and then she opened her eyes again, just 1 month before the fire. With the new chance at life, she vowed to kill and destroy whoever was involved in killing her and her grandpa. She also took back her grandpa's businesses from her toxic, brainless relatives, then turned the business back to its top position in just months, and in her search, she crossed paths with her childhood obsession. The only person who successfully plotted against her and won, but now that she is back, she will get the score even. Drake Williams is the CEO of the Williams Group. Drake was a cold and ruthless businessman and an unwilling mafia lord. When Ana came back, he was pissed, it took a lot of planning and plotting to replace her with her sister in their engagement agreement between the families and send her packing. The girl was a nightmare according to him, but he knew that the minute his grandfather found out that she was back from her hiding hole, he would do anything to get her to marry me, which he would never allow. Although Ana says she has turned a new leaf and proves to everyone with her skills, he would never believe that. Drake knew the devil in her heart; he saw it. Deake believed that there must be a reason why she is back and when he finds it maybe he could use it to get rid of her permanently. Unknown to them, their destiny was long decided. Will Ana find who killed her? Will Drake find out her secrets? Who is the mastermind behind all this?
