Initially, it was all your fault.
You and Sae had meet by fate, paths crossing in the streets of Madrid in ways no one would've ever predict all because you had bumped against him in the sidewalk. And when it became recurrent, for whatever reason or purpose destiny had for it, he had just became more annoyed at the whole thing. How dare you keep appearing in his life when there was no space for lukewarm people like you?
Getting to know you had been an accident as well. It started simple after he had heard you casually mention your favorite color, something irrelevant, but for some reason, it had gotten under his skin and stuck with him. It was your fault for mentioning it in passing, and his fault for allowing the desire to get to know you further to grow roots in his mind.
Little by little, his mind turned into an oasis of information about you — what you liked, what you disliked, what made you tic, the things you sought for unconsciously, the things you loved, everything — like an encyclopedia about you and your existence that had turned so dear to him.
And he let you.
It was his fault for letting you be so dear to him, to the point you could rival with the thing that he had forever loved and put over everything else, football.
It was ridiculous, and it made him sick at times the thought of how much he had granted you power over him, his body, mind and his soul. But he also didn't wanted you to leave.
Not after he had already learned to look for you in crowds, not after being accustomed to associate certain things with you, not after he has grown into the habit of listening to whatever you said and store said information inside of his brain.
You couldn't leave, now now that he yearned to spend his life with you, in whatever way you will let him.
