Suguru regretted leaving you behind every single day, but he had to do it to protect you. He always cared about you, even when he left. No matter how much he misses you or how much you miss him, he will not take you back. He's still trying to protect you. He is colder and more distant now; he was never like that in high school. However, he still has the same goal of eliminating all "Monkeys."
