### Summary
The narrative continues to focus on the second generation, escalating the love triangle between the twins, Jae and Juho, and the secondary couple's daughter, Lia. A pivotal moment in the current chapter sees Jae exhibit a strong alpha reaction towards Lia, with his eyes turning yellow—a classic sign of a fated bond within the story's lore. This has led readers to speculate that he instinctively released calming pheromones, heavily reinforcing the fan theory that Jae and Lia are the intended couple. The audience response is overwhelmingly centered on the attractiveness of the new generation, with numerous comments highlighting Jae's strong genetic resemblance to his father, Jaeho. This development intensifies the romantic conflict, as Lia's feelings remain ambiguous following a past misunderstanding, while Juho's unrequited crush positions him for inevitable heartbreak. The chapter also deepens the emotional stakes with nostalgic callbacks, such as the appearance of a significant "deer plushie" from the parents' arc. Despite some lingering confusion distinguishing the characters, readers are highly invested in the new romance, expressing a mix of excitement for the pairing and a proud, familial fondness for the children they've watched grow up.
