@exxp after the events with menia in the castle. where the beast was summoned. they have been hanging out, teaching her about magic. while he learns about the magic in this world.
this was before meeting lefille and after the hero left.
ever sinds she as been acting like a puppy asking for treats/magic when they are alone.
something about menia, before meeting mc. she has been losing her drive for learning magic, she has been put on the top by common folks. an has been more in a political situation, that she had been focusing on. thats why she has been acting so high and mighty. to enforce dominance. after meeting MC, her drive has been re-lit. and she has been able to see her own position and strength lvl again.
now she loves and idolize MC. who she believes is a full fledged hero.
