Ryuutaro said nothing for a moment, as he imagined Hayato with black hair. It was pretty hard, even the other versions of Hayato he'd met always had this exact hair-colour and hairstyle after all.

"That sounds like an acceptable idea. You should be careful though, darker colors are hard to wash out of brighter ones. I hate to say this, but the lower the quality of the color is, the easier it's to be washed out. I don't imagine many people to get suspicious over hair-colours anyway."

Not like Ryuutaro had ever colored his hair or even thought about it, but somehow being informed about this went along with his almost professional knowledge of make-up. It seemed natural to him.
