Oops! Entering the World of Mary Sue

[Two male protagonists + group portraits + unlimited easy flow + hilarious + fighting + healing] Morning was the beginning of the day. Jiang Chen woke up from the 500-square-meter bed. Lying next to him was blond hair as dazzling as the sun, and eyes shining like gems. Those lips were like cherries, and they instantly made the 500-square-meter bed collapse. Yes, that's right, he wore the same Mary Sue novel that he stayed up late to read before going to bed... And he happened to be wearing the vicious male partner in the Mary Sue novel. What? Want me to be a gay? I'm a straight man! What? Isn't this a Mary Sue novel? How can you let me fight? Why does a Mary Sue world still have to fight monsters? How can we survive in this Mary Sue world? This is a problem... How come this male protagonist is actually a fellow countryman? How come there are so many partners? Why do we still need unlimited dungeons in the Mary Sue world?
