[The title and blurb may be adjusted a little, but the central premise will stay the same]
System: You've been bound to the Everyone Hates You System. You must complete your objective and make the gods hate you.
Xiya: Understood.
And so...
System: The God of Light is aloof and ascetic. He can't tolerate followers who harbor blasphemous thoughts.
Xiya's restless hand caressed the chest of the God of Light's statue. Her gaze was brazen. "O supreme God of Light, I want to possess you."
The God of Light: His ears turned red, and his heart raced.
System: The God of Darkness is forthright and warlike. He hates nothing more than people who are coy and affected.
Xiya brought her acting skills to bear and transformed herself into the ultimate delicate, innocent damsel.
The God of Darkness gently gathered her into his arms. "Don't be afraid. I'll protect you."
System: The God of Love is romantic and sentimental. He values devotion and despises people who are promiscuous.
Xiya had a beautiful elf in one arm and a brawny dragonkin in the other, and even snatched a grape from a succubus's hand with her teeth.
The God of Love's face darkened, but he gently pulled her away from them and growled, "If you keep being such a flirt, I won't let you get away with it."
System: The Sea God is free-spirited and wild. He hates people meddling in his affairs and trying to restrain him.
Xiya: ...Maybe I should do the opposite, then.
Xiya ignored the Sea God, looking at him with icy indifference.
The Sea God wrapped his arms around her from behind, his tail winding around her ankle. He whispered in her ear, "Won't you pay some attention to me too? Hmm?"
Later.
System: The intelligence was wrong. The mission is terminated. The Host will now be erased.
After Xiya died, her soul arrived in the underworld and joined the long line waiting to be reincarnated.
The four gods broke the laws of nature and stormed into the underworld like madmen. Their divine pressure shook the earth, making countless lost souls tremble.
The God of Death, who was said to stand beyond life and death, clung tightly to her leg and wailed, "Please don't reincarnate! I'm going to die too! Somebody help!"
Xiya: ...
Someone asked, "How did you make the gods so devoted to you?"
Xiya replied, "Would anyone believe me if I said they were the ones throwing themselves at me?"
Reader's Guide:
1. 1v1 ending.
2. Maximum Mary Sue, beloved by all, intense rivalry among the men, completely unrestrained, and maybe not much logic.
3. To make people dislike her, the heroine won't avoid spending time with the other gods. At first, she's focused on causing trouble without getting emotionally involved or taking responsibility, and won't commit to anyone.
4. The aloof, innocent God of Light who can't handle being flirted with / the double-standard, protective, gentle and considerate God of Darkness / the tsundere God of Love with overwhelming possessiveness / the wild, seductive, clingy Sea God.
5. The gods are highly prone to convincing themselves they're in love.
Theme: Don't believe rumors.
