While I agree that it's bad to take photos of people without their consent, I grew up in a city that saw a ton of Japanese tourism and they were also notorious for taking photos of everything (including people and things that they shouldn't) and otherwise being pretty obnoxious. Tourists and lack of respect is a worldwide phenomenon.
I swear this rivalry between Eito and Noel for Kei's affection has become weird. All of this got started because Eito and Noel started crushing on Kei when they were in elementary school age. It's weird to have a rivalry based on a crush most probably wouldn't remember in a year
Plus, wasn't last chapter a big moment forward for Eito's character in terms of respecting the feelings of other people? Why is his character relapsing backwards and not respect Kei's feelings just to one up Noel?
