In that life, he was an infatuated snow grass, falling in love with a beautiful and free butterfly. He made a wish in front of the Buddha just to have a happy relationship with it. He had no choice but to go through ups and downs and torture in the cycle of reincarnation. In the end, he was despairing and disheartened. In this life, fate has arranged that they both become daughters. One is lost in the world, searching for the true love that is missing in her heart, and the other is chanting sutras and praying day and night in Buddhism with her memories, just to repay the love debt she owed to her destined lover in her previous life. As memories of their current life surface, where will they go? Can the wish made in front of the Buddha come true?
