In the novel 'Asterion of the Twilight,' I find myself inhabiting the body of Rosalite, the elder sister of Asterion. Despite not being the main focus, I am struck by the tragic fate awaiting my brother, Asterion, who is destined to perish at the tender age of 20. Driven by a sense of injustice after witnessing his tumultuous journey, especially in the realm of BL storytelling, I resolve to alter his destiny. However, my attempts to avert his demise prove futile as Asterion meets his end repeatedly, causing me to revert to a younger version of Rosalite with each failed intervention. Undeterred by the cycle of loss, I persist in my mission, determined to shield him. I vow to thwart anyone – be it a wealthy aristocrat, a regal figure, or a captivating foreigner – who dares to harm my beloved brother, ensuring that they face dire consequences for their actions.
