### Summary
Following the revelation of Euntae Hwang's traumatic past, where he was forced to kill his vampirized parents to protect his sister, the narrative focuses on the tragic consequences of this act. Reader discussion centers on the deep rift between Euntae and his sister, Haeun, who misunderstands his actions and views him as a murderer. Many readers debate whether Euntae should have told her the truth to spare them both the suffering. The most critical development is the confirmation that Euntae is also a vampire with a limited five-year lifespan, which is now nearing its end, creating a sense of impending doom. This has led to widespread speculation that the pureblood vampire Hayan will save him by giving him her blood. The immediate plot introduces a new threat in the form of Haeun's suspicious boyfriend, who is identified by readers as an accomplice to the villains, bringing danger directly into Euntae's personal life. Alongside these dramatic developments, readers praise the artwork and question specific rules of the series' vampire lore, such as a character's sudden visual power-up.
