Teen age girl can be fucking cruel with each other without even a single once of physical violence, they can totally detroy someone with words, and if you add a bit of sibling envy, a dash of immaturity and and an insane amont of puberty craze, it's honestly quite predicable that she's turns into a total dickhead with her ''' perfect'' stylish citygirl sisterI...didn't expect Maharu to react like that, she always look sweet normally.
she grew up i guess.
