About
This is a world where magic and magical beasts run rampant. In the royal capital, a glittering banquet was held for high-ranking parties. It was supposed to be a prestigious event attended by the King, adventurers, and the Hero. —However, tragedy struck suddenly. The Crown Prince was murdered by someone. Three women from the recovery magic party "Lovelies♡" who happened to be present immediately cast healing spells on the Prince. But it was too late; they could not save his life. The tragedy then turned into further despair. The only magical residue left on the corpse was theirs. Falsely accused, the three were immediately sentenced to death for the murder of the Crown Prince. Cain, the Hero who witnessed the whole scene, chose to pursue the culprit rather than save the Prince. The attacker was a general of the Demon King's army with the ability to turn invisible. Cain relentlessly tracked down the general and finally defeated him. He then presented the King with decisive evidence proving the innocence of the three women. Having been cleared of the charges thanks to Cain, the three women developed a fanatical love for him. They began to follow him everywhere, constantly trying to cling to his body. However, the only person Cain loved was his wife. Out of sincerity and consideration for her, he repeatedly tried to push the three women away. But no matter how much he rejected them, they would not leave him alone. His wife, smelling the scent of unknown women on her husband when he returned home, was deeply hurt by the cruel situation where their peaceful time together was being chipped away. She could only see his explanations as the "pitiful excuses of a cheater." Unable to bear it any longer and convinced of his infidelity, she handed Cain divorce papers. Cain desperately tried to tell her the truth and plead his innocence. He helped them out of sincerity, was stalked by the women, and lost the beloved wife who was his one and only. Even so, the harem continues to chase him, directing their obsessive, world-shattering love toward him. At the end of a despair with no escape, Cain's mind finally broke.
