Betrayed by scum, Trise Asa Rich heiress

To repay Sebastian Sterling, the boyfriend who saved her life but left her disabled, orphan Yuna Miller works as a cleaner by day and delivers food late at night, even donating bone marrow to raise the exorbitant cost of her rehabilitation. At a dinner party, she runs into him in a suit and tie and learns that he is the heir to the Sterling family fortune—and that his pursuit of her was nothing more than a gamble. Yuna Miller walks away resolutely, while Sebastian Sterling suddenly realizes he has long since fallen for her. Consumed by remorse, he begins searching everywhere for her.
