|Those potions must be the heroine's doing!|
Zoemi figured out.
Although it was questionable where a commoner girl would get the money for the expensive potions from - but, truth be told the black-haired boy just shrugged it off as a case of a flaw in the game logic – or simply a plothole.
Zoemi would not find it all that surprising if the heroine simply conveniently stumbled upon a whole crate of such potions on the side of the road.
Or maybe she got them from the second prince since his route was so accelerated that it became all jumbled and unclear what will he do next...
But hey - mana potions that could help Zoemi with protecting his master were the exact same mana potions no matter how or from who did the black-haired attendant attained them from!
