I'm honestly will use that reaction a lot if we have one. But please let it contain 0 score, just like the drink, confused, thinking and dumb reaction. It's just a fear, not disliking or anything.
Agree that it should have zero score impact. Sometimes you’re just spooked by a sudden horror panel or creepy reveal, but it’s not the same as disliking the chapter or the post itself. A fear reaction would be fun and pretty fitting for a lot of manga genres.
