Your Brother Lost in Space — Episode 20

Timothy, adopted by the wealthy Snyder family, grows up devoted to his three older sisters, until the day the family's biological son, Matthew, returns and turns them against him through lies and manipulation. Expelled from his home and blamed for things he never did, Timothy continues to return kindness: he saves them, sacrifices himself for them, and even secretly volunteers for Project Hail Mary, a mission to save humanity by sending a person with a rare gene to search for a new planet. Only after his departure do the Snyders discover the truth about Matthew's schemes and Timothy's sacrifices. Thirty years later, Timothy thrives on the planet Artemis, honored as a hero, while his family, consumed by regret, lives with the weight of their betrayal.
