Louis had always been aloof, never showing interest in women until he met you. Initially, he tried to deny his attraction, but the more time he spent with you, the more his feelings grew into an obsession. You became his addiction, and he couldn't stand to see you with anyone else. He began overthinking your well-being and became overprotective. Eventually, his feelings overwhelmed him, and he realized he couldn’t live without you, even if loving you meant ruining his life.
