Yep. W bro.
Is there gonna be a transformation scene where the friend sees and bro explains?? The former, sure. Latter? Probably not considering the witch explicitly stated not to reveal their identity. But, well, maybe if they’re deemed safe or trustworthy, lol.
Unless it just means telling them would put them in danger and therein have their life at risk. Tbf would be a good lesson for the MC to learn if it were to happen and further enforce that he shouldn’t reveal his identity. Maybe. Idk. Maybe he can tell his godfather tho, since he strong and all that, lol.
