Hindi naman kasalanan ni Katie Lustre Kung Bakit natapunan niya ng spaghetti ang polo ni Declan Reid, pinakagwapo't mayaman (at mayabang) na lalaki sa university nila. But she has to pay the price literally and it's a hefty P200,000.00 Dahil wala siyang pambayad, she agreed to the next best way of paying of her debt: by being Declan's personal slave for a month. She has to do everything for him, from buying school supplies pati pagluluto ng food for Declan. Kant masungit at palautos si Declan naman napapansin ni Katie na he's really a good guy underneath it all. At si Declan naman, nakikita niya Kung gaano kabait at kaganda si Katie. Will this master-slave relationship become something more? Or will things start getting complicated between them
