@justforthelulz: The word is "omnipresent". Whether he's also omniscient or simply clairvoyant depends on whether he's aware of the shorthaired cosplay girl's affections or if he's blind to that.
I'm betting he's playing chessmaster in that situation.
I tried holding out, too, but just couldn't do it. I don't think there's anything really lost by reading the Happy Couple series because even if Happy Couple didn't exist it would be beyond insane and ridiculous for Shinozaki and Katase to *not* end up together.
