Estella is an 8. She's so full of herself lmao the idea of being rejected just shortcircuits her. She won't lose her cool in public but she'd definitely get hit hard by it in private.

Everyone else is uhhh more mature. Heather has way too massive a following and too many suitors to let it bother her. Same with Lex. Lionel is more likely to do the rejecting than anything else. Shayla's too chill to be bothered.
