Heir Hidden by the Masquerade

Serena, a poor girl, is set up by her stepfather into a one-night stand with wealthy heir Adrian, who cannot bear to be touched by women—and ten months later, her son is abandoned in an orphanage and adopted by Adrian himself. To find her child, Serena enters Blackwood Manor as a nursing nanny, and through misunderstandings and schemes, uncovers the truth of her son's parentage—finally reuniting with her lover and child.
