Lost Brother in the Cosmic Void — Episode 4

Adopted by the wealthy Snyder family, Timothy grows up deeply devoted to his three older sisters—until the day their biological son, Matthew, returns and turns them against him with lies and manipulation. Despite being cast out and blamed for things he never did, Timothy repays their past kindness with ultimate devotion: protecting them, sacrificing his own future, and secretly volunteering for Project Hail Mary—a mission to save humanity by sending a person with a rare gene to a new planet. Only after his departure do the Snyders uncover the truth about Matthew's schemes and Timothy's sacrifice. Thirty years later, Timothy thrives on the planet Artemis, honored as a cosmic hero, while his grief-stricken family is left to live with the devastating cost of their betrayal.
