Not exactly the most romantic situation, hearing those words. But Haruka was glad he heard them. There's a subtle difference between being told 'I like' and 'I love.' This way he no longer has to be uneasy. Lila loves him, and she even picked him over Austin Kiryu. There's no longer any need to be uneasy, and yet he's even resorted to following her around. Haruka knows she has no other guys, and he isn't following her around because he thinks she has any. But when Lila isn't honest with him, he becomes uneasy.
How contradictory, he's the one not being completely honest with her. His thoughts broke off when he found the blue hair girl staring at him.
"Done stalking me?" Lila said with a smile. It doesn't surprise Haruka, seeing her.
Haruka sighed, "If you knew I was trailing you, just say so."
Lila laughed, "But that wouldn't have been fun."
"Join me." Haruka murmured.
