The plan was that Alicia would be sealed in the Box of Time for six months from that time. With the current cure, she had six months before being separated from Alex. Firia agreed to accept Alex's Fire and when she ascended later, she would bring Alicia. After that, Maxwell would bring them together and train them. After Alicia was sealed, Firia told Alex to ascend as soon as possible, she didn't want him to wait for her. Alex seemed a bit reluctant at first. However, after Maxwell said that he could meet them again sooner if he could get stronger as soon as possible, he accepted his plan albeit reluctantly. So, Alex planned to resolve all of the problems in that world. That way he could be relieved if he was going to leave Firia and Alicia behind.
"Sherry, you will be the one who protects him, especially from a homewrecker," Alicia said suddenly. Firia also agreed with her.
"Wuu!" Sherry nodded.
Alex looked at them weirdly.
