The Billionaire's Weakness, Calliste

Calliste, 19, lives in front of the house of her mother. Her parents had separated and started new families. Emma, Calliste's mother, manipulates her into leaving her father's home with promises of a college education. Emma secretly intends to exploit Calliste for financial gain. Emma, a maid for the billionaire Leone family, discovers Stefan, their son, is returning home. She forces Calliste to work at the Leone estate, instructing her to seduce Stefan. Emma aims to exploit the Leones' wealth, particularly since Isla, her 7-year-old daughter, requires urgent heart surgery. Calliste reluctantly complies, pretending not to know Emma. Her kindness and charm easily captivate Stefan. As their relationship deepens, Calliste genuinely falls for Stefan, unaware of her true feelings. Stefan proposes marriage, gaining his parents' approval. However, Emma's true intentions resurface, urging Calliste to secure the Leones' fortune. Stefan discovers Calliste's initial deception and, heartbroken, distances himself. Calliste, now genuinely in love, is left heartbroken. A month later, Calliste learns she's pregnant with Stefan's child, further complicating their tangled web of love, deception, and desire.
