Once a kid, Rin had been more focused on soccer to think of soulmates.

It hadn't been on purpose, not a decision that had been made out of spite or fear of being held back by it, but rather, he had been too busy trying to keep his pace steady to continue on following his older brother's steps. Trying to fill the shoes he needed to fill in order to fulfill his dream along Sae.

While everyone around him had been eager to meet their soulmates, Rin had been more focused on soccer. It had been something that happened more like an instinct, not an ill-mannered way or thinking, because he hadn't been that way before.

Then, Sae returned after being scouted, and with his return and his path straying away from Rin's, the weight of his decision broke not only the brotherly dream they both had shared for years, but also, something inside of Rin. Sae and his decision deeply affected Rin, destroying a childlike part of Rin that had been waiting, yearning to play along his older brother again. The kind that kept their childhood views, naive and longing.

And with that, Rin pushed away everything, vowing to destroy his older brother and prove himself to the world.

You appearing in his life at the worst time ever had to be some kind of punishment.

He had been determined to keep you at arms length. He hadn't meant to harm you in any way, but he didn't wanted you around. He had goals and plans to achieve and nothing would change that, no matter what. It didn't mattered if his pinky was tugged towards you every time you were near, or if his heart pounded against his ribcage like it knew it belonged beside yours. None of that mattered, you didn't had a place in his life. So he was determined to ignore you.

Except he couldn't. And he found himself caving in your presence, your touch and everything that made you his soulmate.

It was just another proof he wasn't his older brother, because while Sae had always been fine with killing that longing part of him, Rin had been prey of it and had found on his knees against it. He couldn't keep you away, no matter how much he had wanted it, he would always be weak to the bond between you and him.
