In Just One Year- The Billionaire's Wife's Unconditional Love Novel

It was all about a year. Just one simple year. They got married because of his Grandmother's wish. He didn't fall for her in that one year but she did. She didn't expect he would still hold on that contract after being married for a whole year but he did. He terminated the contract after a year and told her that it was over without any regret. He had gifted her divorce papers on their first wedding anniversary. He had expected her to throw a tantrum but too bad cause she didn't. Instead she just packed her bags and left just like he had asked her to. Then all of sudden one year later they met again. But she didn't change like those cliche heroines after divorce. She was the same as she was a year ago. Stupid, clumsy and stubborn. He didn't realise what he lost like those cliche ex husbands when he saw her for the first time after a year. But why did it sting watching her talking to some other men so casually? Why did it sting when she didn't look at him with those puppy lovesick eyes anymore? Why did it sting so much when she treated him like other ordinary people? It shouldn't have right?
