Watashi wo Sukisugiru Yuusha-sama wo Riyoushite, Konse Koso Nagaikisuru Tsumori datta no ni (Tabun, Mata Shippaishita)

I use the hero who fiercely loves me, and in this world I aim to live long! Lizette, a count's daughter, is a "Recaller", or a holder of previous lives' memories, and she is on her fourth life. In her past lives, always on her 20th birthday, she would be killed and eaten by a demon. So to live a long life in this one, Lizette retreated to a remote countryside sanctuary, where monsters don't appear, living quietly and peacefully. However, one day, she, once again, met a noble boy whom she saved in her childhood, Ralph. Somehow, he had become the country's hero, who toppled a demonic king. It may be possible to avoid death by Ralph's side... With this in mind, Lizette accepted his proposal. From now, the serious romantic comedy between the heroine who doesn't want to die and the intense-loving, yandere hero begins!
