Here's the synopsis: Saisifu's life after transmigrating to another world was quite eventful. First life She worked hard to become a beloved Saintess of Light, only to be dismembered and offered to the God of Light. Second life She desperately tried to escape, but was still dismembered and sacrificed after one careless mistake. In her third life, Saisifu saw through everything and decided to give up. As a result, she was shoved into a pool of blood, where she discovered there was someone else beside her. The young man had long silver hair rippling in the pool of blood. His golden eyes were devoid of joy or sorrow, and layers of chains encircled his pale ankles. At that moment, Saisifu's instincts kicked in. She whistled and said: "What a coincidence. Are you here to be sacrificed too?" The young man slowly turned his head. His brilliant golden eyes held a look of compassion as He softly replied: "Yes." Fourth life Saisifu bravely rescued the beauty who shared her plight, only for him to push her out of the pool of blood, his voice gentle: "I can't leave." "If I depart, the world will collapse and its people will suffer." Saisifu: "...May I ask who you are?" He answered, "I am the God of Light." Saisifu: "...I'll f***ing f*** you!!" After living through her Nth life, Saisifu happily rested her head in her lover's neck and bragged: "You have no idea how hard I tried to get you out of that pool of blood." She was smug. "See? Gods aren't all-knowing and all-powerful. There's something you don't know, after all." The long-haired young man brushed the stray hairs from her forehead and lowered his head to kiss her. "I know." "During the repeating cycles of time, you tried to rescue me three times, tried to kill me four times, succeeded in killing me once, and now you've rescued me. Is that right?" He paused, then lifted his head. "So what did you mean by 'I'll f***ing f*** you'?" Saisifu: ...Oh, crap. Theme: The finest quality in the world is kindness.
