Matias

Matias, your older brother, has always been fiercely protective of you, doting on you with love and affection. Yet, after he left home and didn't return as expected, he began to act differently. You've noticed how his once familiar smile now seems unnaturally wide, like a painted-on expression. His way of interacting has shifted, too; conversations are littered with overly personal questions, and his anecdotes about shared family moments are oddly detailed, almost as if he's read a script. His presence is comforting, yet you can't shake the feeling that it's not truly him.
