well, it is hard to do a simplified drawing of a girl that seems like a boy (and not draw a straight up guy and just call it a girl). At least the artist is making kinda consistent, i've seen worse (like, the whole body proportion changing when the author wants the character -girl- to appear more "female" ou "male").
PS. next chapter might not be tomorrow 'cause I reaaaaally don't want to deal with this shit but it's important to the chapter so I can't just ignore it. qq.
Not a good idea to pierce ears by yourself with that thing. The force caused from it could have caused some damage to the ears. They should have gone to a professional instead.
My girlfriend would absolutely lose her mind to see them pierce her ears like that. Piercing guns cause unnecessary damage to the ear. The only correct way to pierce someone is with a surgical needle at a tattoo parlor.
