The biological younger sister is the Mary Sue protagonist of a novel. In the previous life, despite the opposition from our family, she insisted on saving the male lead who was severely injured.
In order to fulfill their deeply abusive love, my parents and I became part of their play, being mercilessly killed by the male lead.
In this new life, I chose to wholeheartedly support my sister, personally placing her on the male lead's bed, allowing him to experience the warmth of "home."
