Maxing Out His Heartbreak, Making My Own Rules

I transmigrate into an abusive romance novel. The system says once I max out the heartbreak score, I can return home. I figure out the rules. Before Julian Pratt asks for my heirloom for his childhood sweetheart, I speak up first and defend my neighbor who "accidentally" breaks the wish jar he gives me. I even give away a very symbolic item. As his face turns pale, the system alerts me that the heartbreak score went up. I smile. Who says only the heroine has to suffer?
