I'll Live a Long Life to Dote on My Favorite Stepbrother!

In the world of a popular life simulation game, a devoted player’s greatest priority is protecting his absolute favorite character. That cherished character exists within the game as his older stepbrother, and the player has spent his time navigating the virtual world solely to ensure his safety and happiness. However, everything changes when the player suddenly finds himself pulled out of reality and reincarnated directly into the very game he knows so well. Rather than waking up as a powerful hero or an outside observer, he discovers that he has been reborn as the younger stepbrother—the exact character whose original storyline was destined to end in a tragic death. Now trapped inside the simulation with full knowledge of the grim fate awaiting him, he faces a desperate struggle for survival. To protect his beloved older stepbrother while simultaneously rewriting his own doomed ending, he must use every ounce of his knowledge about the game's mechanics. Determined to defy the script, he resolves to live a long, careful life dedicated entirely to doting on and safeguarding his favorite character.
