I’ve Been Reincarnated Into a Female-centric Novel, Entangled with Yandere Sisters

(Rating just released, will rise) [Growth-oriented yandere] + [Multiple heroines] + [Redemption] + [Scandalous situation] Jiang Xun transmigrated into the popular female-oriented novel he had written. A wronged child who was used as a pawn by his childhood sweetheart throughout the entire story, and died without ever knowing how he had offended the female lead. Original ending: The female protagonist, after being corrupted, was imprisoned in an underground chamber and tortured for a year, eventually being frozen into an ice block and displayed in her bedroom. Jiang Xun didn't want to be a human ice sculpture, so he started desperately trying to win over the female lead, Pei Zhiyi. But he was a low-level writer who had been writing melodramatic stories for three years. He had never been in a relationship, so how could he know anything about normal ways of getting along? As a result, the favorability rating was raised, but things started to veer off course in a direction he had never written about before. Pei Zhiyi's gaze towards him became increasingly strange. "Jiang Xun…you waived my rent back then, now I'll give myself to you as compensation, okay?" You won't refuse me, right?
