He is not a pervert
If Rui Fei was a Gen Z type of teenager he would have spent half the night searching on Baidu or Google 'How to dress my crush's wound?', 'Is it okay to undress my crush to treat his wound' or 'am I a pervert for undressing my crush to treat their wound.'
His browser history would be full of this kind of nonsense if he had the time and the means but because he didn't have that he had to do what he had to. He reached over and unfastened the belt on Ji Yao's clothes. His face was serious like he was performing brain surgery but in truth, his heart was racing like a bullet train.
His hands were trembling slightly as he pulled apart the lapel of both the outer and inner robe. Ji Yao's smooth chest was immediately exposed making Rui Fei gulp with his eyes curiously glancing over his undulating chest. Oh, how he wished this wasn't an emergency situation.
