I don't know exactly how old Utou is, but he and Sumi are 12 years apart
you can see a comparison of all the characters here :) https://harmonia17.tumblr.com/post/179804506257/tinyrambling-source-the-age-difference
uh, thanks, then he must have above 20. Conventionally, high school lasts 3 years but there's some options were it lasts just 2 and university can last from 2 to 4 years; so the worst case scenario, Sumi could have been 19, but it's a relief he hasn't
yeahh..in the first chapters there's a flashback when he was 18 ... I don't know how much time has passed but I guess he's between 20 and 22, so young compared to Utou >_<
I know (‘◉⌓◉’) he was 17 in the flashback of the first chapter and 18 in the extra where he is getting his job in the host club
although I was worried that only 2 years had passed between the time he was attacked at school and now at work
Someone knows it? I know that Utou has 30+ and I used to think that Sumi was 22, but I was remembering what I had to investigate once about the educational sistem in Japan, and it hit me that he could be younger
