This Mu Yexun guy must have been single for his whole life, for his girl to be his right hand like that... Someone should take this guy outside to show him how the world works.
I dunno, I didn't read it. I just wanted to make a joke like this when I saw the advertisement on the app that said his right hand transformed into a girl. If you don't get the joke, that's okay; this is not a serious review anyway, you can just skip this review.
