## Chapter
- number: 47
- release_date: 2025-03-08

### Summary
The primary mission to prevent the protagonists' siblings from meeting has been completely supplanted by the urgent investigation into a stalker, who is now presumed to be their future killer. The latest chapter has solidified overwhelming reader consensus that Mirim's boyfriend, Sejoon, is the culprit. His on-panel behavior is described by the audience as intensely possessive, obsessive, and a significant "red flag," confirming long-held suspicions. Some readers have even begun forming theories that directly link him to the future tragedy, citing his driving lessons and a missing red car key as foreshadowing for the fatal accident. As suspicion consolidates around Sejoon, other potential suspects, like the freshman Yoojin, are now largely considered innocent by the readership. Meanwhile, the clandestine romance between Haneul and Dahae continues to develop, with readers noting their deepening intimacy and flirtatious interactions. This personal dynamic, combined with the hunt for the stalker, has become the story's central conflict, leaving the original goal of keeping their siblings, Taegang and Mirim, apart seemingly abandoned and failing.
