I just don't get it why noxia would ever interact with people that badmouths her sister like if she really is a good person shouldn't she be telling those people that if you talk shit about my sis don't talk to me anymore
Like I don't even have a good relationship with my own sis but I know nobody would dare to talk shit about her in front of me and expect me to keep in touch with them anymore
This is the usual case in every other manhwa ppl don't like fl talks shit about fl in front of her family and her family that is oh so pure can't even hurt a fly doesn't do or say anything about it and pretends nothing happened and the poor fl who gets bullied everyday just for existing starts to defend herself and becomes the villainess
