Although I am not as good as the hero, it’s okay not to let myself be cannon fodder!Eh?Wait, what's going on with this plot, did the agreed hero fall in love with the heroine?Su Binghang looked at the indifferent face that kept approaching, and sighed helplessly——What kind of experience is it like to turn Mary Su's novel into a Danmei novel?Probably because I have to worry about my ass every day...
