Why is everyone cheering on Fuuko? She's a fucking bitch, and I don't like that word but it's the one that fits better. She's possessive, selfish and nothing justifies to hit someone else, even more if it's a friend of yours, you can be angry but never hit. Your friend can have their secrets and you can't get them out of them by hitting.
Here cheering on Konomi and hating on possessive violent Fuuko.
