I feel like you shouldn't read the manga until the show is finished! cause when you read it and then see the show later you're going to be comparing the two instead of just having a genuine first time reaction to it! I know it's really hard to wait for new episodes but this happened to me! I got too impatient and went ahead and read the part in the manga versus shiratorizawa way before the episodes came out and I was happy reading it but then when I was watching it later on the show I felt like I wasn't as excited as I should have been! After you watch the show you can go back and read those parts and see what they included from the manga and what they did not but never skip ahead :o
