Sick Family Never Regret, But I'll Make Them Pay

Synopsis

I went to my grave still wondering why my parents only loved that fake heiress even after they got me back. Why did even my own fiancé choose her over me? I died in that moldy rented room in the slums. The stomach cancer pain kept me curled up all night long. Even in my final moments, I still naively clung to the hope that my death would at least make them regret, and that it would finally dawn on them: I was the one they'd loved all along. But when my soul drifted back home, what I saw was the fake heiress beaming in her wedding dress, while my parents were busy with her wedding preparations. And my ashes were scattered like garbage among the rose bushes in the garden. No one remembered me, nor did anyone mourn me.
