Review Detail of Pure_Lead in Reversed world

On chapter 2 the MC sees his appearance in a mirror, staggers, slips, hits his head and faints. What a stupid way to faint. These shi**y authors are always too lazy to write believable characters so they make them faint so they have the carta blanca to skip ahead, how stupid. How can a dude literally physically stagger himself only because he think he won't be a '170cm chad' and almost kill himself in a bathroom. Of course the author is trying to make things as convenient for the transmigator as possible because conflict is boring or something, and the stupid protagonist instead of thanking god for his mercy he insteads starts complaining, those are all signs of a trash wish fulfillment story, and a spoiled brat of a main character that will whine and moan if everything isn't going according to his wishes.
