Lost in Space for My Sisters — Episode 20

Adopted by the wealthy Snyder family, Timothy grows up deeply devoted to his three older sisters—until Matthew, the family's biological son, returns and turns them against Timothy with lies and manipulation. Ostracized and falsely accused of crimes he didn't commit, Timothy still responds with kindness: saving them, sacrificing for them, and even secretly volunteering for "Project Hail Mary"—a mission sending a single person with a rare gene to find a new planet and save humanity. Only after his departure does the Snyder family uncover Matthew's traps and Timothy's sacrifices. Thirty years later, while his family mourns the cost of their betrayal, Timothy successfully completes his mission on Planet Artemis and is honored as a hero.
