The Protagonist And The Reader Must Be In Love

An internet troll who wanted attention, the reader criticized his favorite web novel, saying: “The protagonist is dumb and the author is s*upid.” Author: “…Got it.” Unfortunately for him, the author actually listened to his (troll) feedback. The formerly lighthearted tale of a cute harem master suddenly became super dark and edgy. The reader could only helplessly look on as the protagonist was ab*sed and betrayed, finally embarking on the road to becoming completely evil. Everything was a mess! After that the reader transmigrated into a strange world. How come the person in front of him looks like the protagonist (evil undead version)? Just what is going on?!
