"I will always love you." A promise that sounds empty to you, a sigh of warm air brushing your lips.
Suguru kisses your lips one last time before leaving you. Leaving everything, actually. He had already said goodbye to the others, he had already made the decision to take a path that none of you were willing to follow. Not even Satoru. Not even you.
"I’m sorry," he mutters, but it’s not entirely true. He’s sick of watching his friends die. He can’t live in a world where non-sorcerers used sorcerers, even if he has to leave everything behind.
He can’t bear the idea of the world going on like this.
He can’t bear the thought of losing you either, but to ask you to follow him would be too selfish. He knows better than that. Leaving you under Satoru's care is probably for the best.
