### Summary
The chapter escalates dramatically as the menacing Seo Seunghyun lookalike, previously identified by some as Mr. Kwon, confronts Lee Youngjin inside his home. This antagonist, described by readers as both handsome and dangerous, interrogates Youngjin before injecting him with an unknown and suspicious drug. The readership is thrown into a state of intense frustration and confusion by Youngjin's reaction; he displays a shocking lack of self-preservation, passively offering his hand and allowing the injection to happen without any struggle. This inaction has become the central point of reader discourse, with many questioning his survival instincts while simultaneously expressing fierce protectiveness and fear for his safety. The incident violently re-centers the criminal underworld plot, sparking confused speculation about a mysterious stolen item, an auction, and a figure known as "Sir." The stakes are amplified by widespread reader concern that Youngjin may be pregnant, making the drugging a direct threat to a potential child. Overwhelmingly, the sentiment is one of alarm, anger at the intruder, and a desperate call for Seo Seunghyun's intervention, whose failure to protect Youngjin is heavily criticized.
