After Prison, I Became the Gang’s Darling

The Female Lead Is an Undercover Agent, and the Male Lead Is Either a Gangster or a Drug Lord's Son. I Forgot

I saw this while scrolling before: The female lead has been undercover for seven years, and I think she's seven months pregnant. The male lead discovers she's an undercover agent, locks her in a basement, and forces her to miscarry. He personally takes the aborted baby away. Five years later, a child enters the basement... That's roughly what happens.
