@Haikanouch_ique If anyone wants to know Lina's true nature, novel spoilers below
Spoiler!
She's not malicious to begin with, she's just a naive idiot with no sense of decorum. She's selfish and only cares about what other people can do for her so she sometimes comes off as malicious but she's really not smart enough to do any of this intentionally. She will become malicious later tho due to some information she receives.
