It's valid to call her a kid when she's around adults tho, there is a stark difference between a HIGHschooler a bunch of grown men in their 30s with like 8+ years of hunter experience
And*
shes actually 17-18 not 19
She may be younger than others but not a child, it's a young woman or teenager at most (in my country already an adult) but kid no
I know someone very older may see her that way but she isn't
That's all for my rambling its late and im old that's why i can't hold back anymore
It's off topic (not so much)
Stop saying gaeul is a kid/child when she is already 19, that's confusing (and make me feel very old lol)
Ps: the fact in some countries is a minor or not its another thing but she isn't a child (sorry for the rant i couldn't hold it in anymore)
