Daphne and Aaron knew about each other's existence since ever through old family ties.
A successful architect, Daphne Vincent didn't want to marry, specially not Aaron Nicholas. She was happy designing homes for others, but one for herself was not her idea, till now. 'Low expectations from people leads to high self satisfaction'. One can only be heartbroken once in your life, right? After that, you got to pick up the pieces and move ahead stronger.
Aaron on other hand married only for the sake of his family. 'Love is for fools and marriage for the one who is in possession of some wealth'. Of course one needed a wife to come home to. And idea of an arrange marriage suddenly didn't sound that stupid.
