Watashi ga Akuyaku Koushaku wo Tasukeru Riyuu

Belona Rosentin had been living peacefully as a mere side character in a novel until she became trapped in a death loop that reset regardless of her choices. Desperate to end her agony, she tries a new gamble: stop the novel’s villain, Deminic Roxellen, from meeting his tragic end. But as he opens his heart to her, guilt and unease creep in, forcing her to remember why she chose to help him. Belona is here to break the cycle, not grow attached only to die and lose everything again! (Source: Tapas)
