Valery couldn't fully refuse those words, as deep down her heart there were still some lingering such feelings, but slowly those feelings were being dissolved and dispersed by staying beside Roy.
Even though this guy wasn't a saint or a great knight gentleman, he surely was a true man that cared and took care of her and her close ones.
Not only that, but even her bonds and ties to the other ladies and those kids had grown willingly or unwillingly during this time, and it was at that moment that she understood she couldn't just leave them behind.
In other words, even though she still didn't consider Roy as the center of her world, she wasn't far from it. So, she had no intention of bringing trouble to him.
Not to mention that Roy was the only one who could connect to that Other World, and if she wanted to actually meet her 'mother' and the rest again, she had to be by his side.
"Don't worry, I will never do something like that! I swear!"
