I hate Ijuuin as much as Haitani in Sekakoi -_-

Same. He's annoying. He's everywhere. He wont give up even though we as the reader know he has 0 chances. But still he persists. It's also downright rude because he is openly pursuing someone in a relationship and trying to be a homewrecker (at this point are almost like a married couple). Imagine a guy/gal like him going after your lover after being rejected multiple times. I'd have to slap a bitch.

Agreed. I just want him to meet Haitani or Yuu from SIH and for them to get together so that they can shut up and be gone -.-
