Heir-Raising Daddy Issues

Transmigrating as the background character Erusha Shablin wouldn't be so bad if her father, Leonardo, weren't such a menace. At this rate, the story will play out exactly as written: eviction by her grandfather followed by a tragic death. To avoid her canon ending, Erusha must prove her worth and win her grandfather's approval—but that would be far easier if he weren't constantly angered by her father's antics. Can she navigate this multi-generational "daddy issues" disaster?
