### Summary
The narrative delivers a monumental plot twist that has left readers simultaneously shocked and thrilled, revealing that the obsessive stalker and antagonist, Sejoon, is also a time traveler. This revelation, which many readers suspected but were still stunned to see confirmed, fundamentally redefines the protagonists' mission. Their purpose is no longer simply to avert a tragic accident by keeping their siblings apart, but to actively combat a fellow time traveler who orchestrated the original tragedy and has returned to the past to ensure it happens again. The reader comments are dominated by a mixture of horror at Sejoon's long-term, creepy obsession with Mirim and awe at the story's bold direction, cementing its shift into a high-stakes psychological thriller. This development reframes the entire conflict as a direct confrontation between opposing forces who both possess knowledge of the future. The tension is further amplified by a critical error noted by readers: in a moment of panic, the protagonists have revealed their own time-travel secret to their nemesis, escalating the danger and setting the stage for a terrifying battle of wits.
