Even if Ryuutaro's tolerance of cold temperatures was way higher than Hayato's, he had to agree that it was getting a bit uncomfortable.
So he nodded.
"Shamefully that seems necessary..."

He wrung out his hair as good as possible and then stood up. Well, he wasn't as sore as before anymore, so thankfully climbing out of that bathtub worked well. Immediately he grabbed a towel to wrap himself in, feeling a tiny bit relieved to not be completely exposed anymore.
As Hayato followed, he handed him a towel as well.
