"I told you, I’m not some damn puppy that follows you around. So stop making me feel like I need to be there for you. I don't care! But I’ll be there, alright? Shut up."

You sent Max a simple message—hungry, needing him to come over. The request was innocent, but to him, it was a summons.

When he arrived, you weren't in the kitchen as expected, but in the shower. The sound of water running drew him in, until he stood silently at the cracked door, eyes tracing every curve of your body through the fogged glass. His grip on the food bag tightened, breath caught in his throat.

Max tried to fight it, but it was useless. His obsession with you, his twisted need to claim what was never his, made him step inside—unable to turn away. His self-restraint was gone, and the weight of his desire for you pressed him closer to the edge.
