My Love Lasts Three Months

At death's door, Chitose Chiyo became bound to a System: [LOVE&LOVE System]. At its core, it was a love-for-life exchange system. The only item in its store was her remaining days of life. As one of Japan's most famous idols, she sold her fans dreams and love. If their love for her were converted into data, the resulting number would be terrifyingly large. For her, this should have been a simple transaction. But Chitose Chiyo stared at the exchange screen and fell into deep thought. In the end, she wrote down the following rules: 1. Exchange the love I feel for other people for days of life. 2. One-sided love counts as love. Focus on secret crushes, and never confess. 3. According to my calculations, switching targets every three months is best. The System then offered her several choices. She could pick one person as the object of her "love." Her feelings for that person would be converted into a specific number that she could exchange for days of life. System: "So, who will you choose?" Several cards floated in front of her: [What's the greatest misfortune? When even breathing hurts. When you don't dare touch even cotton candy.] [What's the greatest misfortune? Being alone is what makes you strongest. Even the Six Eyes can't see into people's hearts.] [What's the greatest misfortune? Even a king can't save his clan. A sword hanging over your head is proof that you are king.] Chitose Chiyo: ???? Chitose Chiyo couldn't make heads or tails of it, and was deeply shaken. She picked one at random, then transmigrated. Chitose Chiyo: !!! Wait, transmigration comes with the deal too?! * Chitose Chiyo was the perfect lover. She loved you in silence, deeply and completely. She would brave wind and waves for you, overcome every obstacle, give everything she had, fulfill all your wishes, and carry out your every desire. Even if she never confessed, who wouldn't be moved by such sincere love? But just as he was about to return her feelings, she disappeared. He wanted to find her. * Later, Chitose Chiyo gathered enough days of life and happily severed her connection with the System. Then the worlds merged. They saw the girl shining on the big screen, glanced through the information they'd found, and came looking for her one after another. "Just how many good brothers do you have?!" A group of people, eyes red, asked her, "Did you really love me?" Chitose Chiyo was so startled that her face went blank. After a long pause, she sighed and answered solemnly, "I swear on my life, I once loved you." Her love had all been real. It just had a slightly short shelf life. Reading Guide: 1.
