I've Been Possessed by So Many People, This World's Gone Crazy

[Two Male Leads] + [Reverse Transmigration into a Book] + [Power Couple] This world was a novel. When Shen Yan found out, he could only think how absurd it was. But then a mountain of evidence was laid before him, and he had no choice but to believe it. The people around him started acting stranger and stranger. The news on TV became increasingly horrifying, and one day he even woke up to find that an entire island nation had vanished… People around him began making one bizarre comment after another. Book Transmigrator A: This is a world for people with supernatural powers! Come join us and have a blast! Book Transmigrator B: Hahaha! I’m going to rule the world! I’m the new protagonist! Shen Yan: … One day, a mysterious organization came to see him and politely invited him to their headquarters. Shen Yan showed up as agreed. A flamboyantly dressed man greeted him with a kiss on the hand and a bright smile. “Hello, Doctor. I’ve heard so much about you.” Shen Yan: “…Isn’t a kiss on the hand meant for a lady?” The man kept smiling. “Can’t it be for a partner, too?” Shen Yan: “Who’s your partner?” The man: “Well… The book says the two of us will be inseparable, as close as brothers, share the same ideals, stand together through thick and thin, and be one and the same… I think the only person I’d describe that way is a partner.” Shen Yan: “Then you’re wrong. The author of this book is a foreigner, after all.” The man: “Oh? Would a foreigner describe two close friends as being as intimate as lovers?” Shen Yan: “???” Is this really the villainous leader everyone should be afraid of? Shen Yan: “Nice.”
