Kiryu immediately noticed something was wrong, "Rosalia, calm down," but the girl shook her head.
"I'm beautiful, smart, and talented too. But, all the guys - no, you only have eyes for her. Why? Tell me already, I've never understood it, and things make even less sense to me now. Don't you see Kiryu-kun? Lila-chan will never return to you; she's in love with Karashima. But even with the truth laid out in front of you, you're still looking only at her."
Kiryu didn't understand why Rosalia was acting like this now. Sure, if she said this stuff before when he first went out with Lila and a few months after. Then he would have taken her seriously, and yeah she did do this before, and he sympathized with her. However, now? After so long? This past year they've barely seen each other too. She stopped coming to see him and even changed her number. When Kiryu realized that, he figured that Rosalia had finally moved on and it relieved him.
