The Whole World Is Head Over Heels for Me [Book Transmigration]

[Congratulations, you are now the heroine of this story!] A bolt of lightning sent Gu Lian into an 18+ Mary Sue novel, where every character would fall head over heels for the heroine at the drop of a hat! His mission was to pose as the heroine while keeping his male identity secret, fool all the NPCs, and fill in the plot holes left by the author, who had abandoned the story. Of course, “filling in the plot holes” meant getting doted on by his older brother one day, his father the next, and his fans every day. The only exception was the male lead, who tried his hardest to strip him every single day! Luo Zhaoyan smirked. “I heard that if I strip away your secret identity, the System will cut off your extra parts?” Gu Lian felt a chill below the waist and immediately, wisely, flopped shyly into the arms of his mortal enemy, who had transmigrated into the book with him. In a falsetto, he said, “Have mercy, big brother~” Luo Zhaoyan: “...” Oh no, is this what it feels like to fall in love?! A timid yet flirtatious bottom, and a younger top who seems sweet but is actually devious. Luo Zhaoyan: “Who are you calling big brother? I’m so much younger than you.” Gu Lian [indignant]: “You’re bigger than me in every way, big brother!”
