Hmm, I actually thought of that. But... My stupid mind already put the title as 'Fire Mage' and then .... You know the rest. It's kinda forced even to me, but nothing can't be changed now.
so you wrote yourself into a corner before chapter 10? at the very least, Darkness mage should cost the same or less exp, that way readers dont feel scammed about the MC selling his potential short for convenience.
So he was stupid enough to get betrayed, smart enough to escape, but stupid again to use land deeds to get loan to buy potion when he knows he is being scammed. Idiot. Idiot MCs are not entertaining to read about.
