When will she grow?? I think I forgot that there’s a plot behind her being so small

It's her mana or something like that. If I remember right it needs to be "unlocked" but the only person who can do that is the emperor but if the emperor knows then he would use that to his advantage to blackmail FL's dad/family

oooh i remember now thank youu

Yea but now it’s been unlocked at the academy so she should start growing now
