### Summary
The central conflict escalates as an aggressive alpha, who had been pursuing Yeon-woo, reacts violently after being rejected. This provokes a furious and protective response from Kim Shin, who appears poised to seek revenge on Yeon-woo's behalf. This development has further polarized reader opinion; while many find his anger attractive and his possessive determination romantic, others are increasingly concerned, doubling down on labeling him a manipulative "red flag" whose obsessive tactics are comparable to the antagonist's. Despite the debate, moments of levity, such as a flirtatious exchange via handwritten notes, were well-received. The chapter also introduces new dynamics, revealing Kim Shin's supportive group of alpha friends. A significant subplot emerges with a new character, an informant referred to as "glasses guy," who is caught in a perilous situation after revealing information he was paid to keep secret, causing readers to fear for his safety. Amidst the drama, speculation continues to grow around a powerful "uncle" figure who seemingly commands his own gang, while a cliffhanger ending leaves the fates of several characters uncertain.
