Bad Women Everywhere? That’s Just the Hidden World Unlocked by a Bug

(Also known as: I Turned a World Full of Bad Girls into an Adult Version.) This world is full of danger! The little sister next door I've always looked after frames me, the siblings I took in as children stab me in the back, and the childhood friend princess I trusted most tramples me underfoot. Have good people really fallen behind the times? It wasn't until Su Hao was reborn and turned bad that he discovered the correct way to unlock the world. A tea-sipping little sister is best suited to being a puppy. With a little encouragement from me, she even boldly turns on her own noble mother. The obsessive sister who acts like a devoted servant works hard every night to keep her beloved little brother safe. The arrogant princess may act disgusted when tempted, but she'll still obediently get down on the floor, hoping for my support in the future. Goddesses, empresses, princess consorts... It turns out all these bad women have a whole new side to them. The protagonist? Killing him would be no fun. What's the cruelest blow? Let him know how deeply his fiancée loves him, then make her serve me for his sake and beg me to spare his life. Like when the protagonist's disciple is training hard outside, while the immortal maiden master bites her lip and tempers her heart within. It hurts! It hurts so much! So this isn't a world crawling with bad women after all. It's an alternate world, and I had the unlocking method wrong. Everyone, I'm really such a bad guy!
