Mia and Mark, married for 10 years, struggled to have a child and eventually turned to adoption. After months of paperwork, they brought home a sweet three-year-old boy named Sam. He settled in quickly, even calling Mia “mom” within weeks. Everything felt perfect—until one night, Mark offered to bathe Sam and suddenly ran out, shouting, “We must return him!” Confused and heartbroken, Mia questioned Mark, who claimed he was overwhelmed by fatherhood. But Mia sensed something deeper. That night, she remembered Sam had a birthmark on his foot—identical to one Mark had. The next morning, she confronted him.

Mark broke down and confessed: years ago, during Mia’s IVF treatments, he had a one-night stand. He now believed Sam was his biological son. Seeing the birthmark triggered panic and guilt. Devastated by his betrayal, Mia ended the marriage. Mark signed over full parental rights to her. Though he occasionally sends birthday gifts, he’s no longer part of their daily lives. Mia chose Sam—her son in every way that mattered—and never looked back.
