"If this bear had that kind of potential, then you..." Fey looked at his brother with realization.
Fein knew what was going on with his sister's head. "No, I'm not S-rank yet..."
"Yet? So you are closer?" Fey noticed this and asked.
'Fey is really intuitive.' He couldn't help but notice this. Even when he first transmigrated, his sister is the only one who had come close to discovering his secret. Though she was naïve at that time. Fein knew that if the current Fey is the one with whom he had interacted on his first day, he knew he was fucked.
"Yeah, just a month or so is all I need." He smiled. "But first... I need you to help me make mom agree for him to stay on your side." Fein pointed at Voli.
Voli subconsciously puffed his chest.
Fey looked at Voli once again. After thinking for a while, she understood his brother's intention. "You want Voli to guard us? Specifically, mother?"
Don't forget to use your power stone :)
