This niece is another piece of "girls written by men", so unaware, no cue, no clue, slow af. Makes me frustrated cuz this is bad writing. (/TДT)/

Characters like her is why we don't like women in shonen/action... take The 100th Regression of the Max-Level Player for exemple... his little brother is in a even weaker position than her... and is even more spoiled by him... he's been in less danger than her and had everything to be naive and put him in danger accidentally... but it doesn't happen... he does literally nothing and manages to be more helpful than the niece...
Id hate Se-ah even if her gender was reversed... but every time it's an extremely unhelpful side character the mc cares for... they make it female...
Tough love. ╮( ̄▽ ̄)╭
