>>101225305I get that this is 4chan and people here use a certain type of lingo, but when you say cute or adorable certain images come to mind.Suggesting a serious female character do something cute just comes off as you asking to get your cutesy fantasy itch scratched from content that isn't meant to achive that goal, sure, maybe you just meant give her a hobby like playing an instrument or sport, but to people outside your head it sounds like something totally different.
The correct way of going about it would be suggesting she be humanized when she has time to relax, that's something every character meant to be even semi human needs.
But just blurting out "make her be cute" is not only useless, but seemingly a call for turning her into some fantasy waifu so you can fantasize about protecting her smile.
