Billionaire's Accidental Twins

Mina's mother takes her tuition money to cover the gambling debts of her brother, and Mina is left with no way to stay in school. She takes work at a bar, where a customer harasses her and Lucian steps in. They spend the night together, and the next morning he takes something she says as a demand for money and leaves. Mina turns out to be pregnant with twins. Lucian's mother takes her in, and once Lucian learns what actually happened he comes back for her and gets her out from under her brother's creditors. She returns to university and is bullied there, and while all this is going on she finds out she is not her mother's biological daughter. A rival for Lucian pushes her, which brings on an early birth, and later has her taken. Lucian deals with it, and the two of them marry.
