### Summary
A significant ideological conflict has erupted between Haneul and Dahae, fracturing their core mission. Dahae now argues that their siblings, Mirim and Taegang, are fated to be together, and that their continued attempts to prevent the union are futile. She proposes a new strategy: allow the relationship to proceed and focus instead on finding an alternative way to avert the future tragedy, aligning with the theory that they must unmask a potential murderer. Haneul, however, remains rigidly committed to their original plan of keeping the siblings apart. Driven by the trauma of his brother being his only living family, he is perceived as stubborn and unwilling to listen to Dahae's perspective. This fundamental disagreement has created a major strain on their own romance, with their communication breaking down. Readers are deeply conflicted by this "moral dilemma," acknowledging the validity of both positions but largely siding with Dahae's reasoning as the more pragmatic approach. The consensus is that the true mission is no longer to prevent a fated love story, but to solve the underlying mystery of the stalker and potential involvement of the new suspect, Sejoon, to change their siblings' destiny.
