For My Derelict Favorite

I found myself inside my favorite romantic fantasy novel! Though I’m just a commoner, I’m incredibly wealthy. I stayed on the sidelines, quietly observing the main couple’s love story, thinking I’d return to reality once the novel ended… But the story finished, and I’m still trapped here! Worse yet, I discovered dark secrets I never wanted to know—like how my beloved second lead, Kaelus, met a tragic end. Without him, I fell into poverty, grew sick, and died too. I expected to wake up in the real world, but instead, I traveled back in time. This must mean… I have to save him, don’t I?
