The hair-ruffle annoys Ryuutaro beyond belief. Just who did this guy think he was, ruining his hairstyle like that?
And, yes, he was special, thanks for noticing and yes, Hayato could be quite annoying. But Shamal wasn't allowed to say that. He just wasn't allowed to talk badly about Ryuutaro's boyfriend.

"I am aware that he's rushing things a bit from time to time, but you shouldn't say it like that", Ryuutaro smirked, "It can be very easy to get along with him."
For him himself at least.
