### Summary
The chapter reveals the hilariously unhinged negotiation between Edwin and Duke Haven. In a bid to secure a husband for his sister, Edwin threatens not Haven himself, but to start a war with the northern neighbors. To everyone's surprise, this threat only excites the Duke, whose polite facade shatters to reveal a "lunatic" personality that rivals Edwin's own. Readers are thrilled by the revelation, with many commenting that the "girlboss" empress is now flanked by two "murder hobos." This shared thirst for chaos has solidified the fan theory that all three main characters have retained memories of a past life.
