Anime/manga pet peeves

What are some of your biggest pet peeves when it comes to anime/manga?
It can be very specific (like specifically about one character) or even something in a whole genre.

LET YOUR RAGE of minor or big annoyances FLOW ONTO THE PAGE as you type. (╬ಠ益ಠ)و✧

(also I just want to clarify this isn't specifically for yaoi or bl it's for every genre :D )

Ok for me, I always HATED animal people in shows that have animal ears AND human ears sooooo much. it just pisses me off, LIKE PICK ONE!!! The echo must be hellish smh. rip.

also Khun Aguero from Tower of God (specifically in the anime) I have a beef with. Super cool, one of my fav characters, best boi, but.... each time I see his blue hair thing it reminds me of a god damn sticky note. I can't unsee it. *sigh* :'D
