However, making Ace give up on them was simply impossible at this point because of the Thief House. He had already told her that anyone who joined the Thief House couldn't leave.
So, if he had any intention of opening a spot for her, he could've easily just gotten rid of one of the existing members and opened a spot for her.
She wasn't a fool who would think that Ace never thought of it. But she was wise enough to figure out that Ace had no intention of getting rid of the existing members despite their past conduct against him.
Now, she could even see more clearly that Ace had no plan of stopping at just those three female members as he already had one in his space ready to join when the spot opened.
She had never thought that the naïve yet cunning boy would turn out to be like this after just fifteen years, and he had experienced so much in these years that some people won't even experience a fragment of it in their entire lifetime.
