The Billionaire's Forbidden Secret My Sister's Baby Daddy

Years after their bond as childhood sweethearts was broken, a billionaire CEO crosses paths again with the person he never stopped seeking. The reunion is complicated by lost memories and a stark change in temperament: one is now a cold obstetrician, while the other remains strong-willed and possessive. Old feelings return alongside unanswered questions about what happened between them. The situation becomes more fraught when the CEO learns that his sister is carrying a baby conceived through sperm donation. The donor is tied to the person at the center of his unresolved past, forcing him to confront a painful misunderstanding and difficult moral choices. As affection collides with resentment, hidden motives, revenge, and the responsibility surrounding the pregnancy threaten to reshape their reunion before the truth can finally emerge.
