Ryuutaro really hated being touched and Ryuutaro really hated getting help like this. Currently he also about hated everybody and anybody. But more than all of that he hated waking up right now. So even if he was half-conscious of what was happening around him, the more graceful solution was pretending to be completely asleep. Because he totally wouldn't let an almost stranger carry him like this when he was not completely knocked out.
But even if he had tried now, he wouldn't have been able to walk himself anyway. And if so then not very elegantly.
So as both options were unpleasant, he settled for the less exhausting one and kept his eyes closed tightly.
