Don't feel bad, Flan is a bitch and we take shots at her from all directions. Are you pretending to be this hot shit beautiful kawaii idoru model who can do no wrong?
Because you know, Flan does. It's not like we're all perfect and go out in the street and rip on everyone we see.
Flans ugliness (inside) just magnifies all her external flaws. The harder she tries and the nastier she gets the uglier she appears to us.
