Ryuutaro didn't notice how much the blood on him had actually been bothering him until he got a real chance to get rid of it.
Getting changed in front of Hayato didn't bother him anymore either, he still thought it was rather... unelegant to change in front of someone else, but it was not like Hayato could see anything he hadn't seen yet.

The colors of the top and his hakama naturally clashed a lot, but right now Ryuutaro didn't even care. He was just glad to wear something clean again.
As he finished getting dressed again, he looks over to Hayato in case he should need help or anything.
