### Summary
Following the arrival of Yuyeon's younger sister, Yubyeol, the narrative immediately explores her previously established connection to Jaeyoon, the younger brother of Bareum's former crush, Jaehyun. Reader comments confirm this subplot takes center stage, recalling that Yubyeol was the girl who gave Jaeyoon candy in a prior scene. The chapter's key development is a moment of sudden discovery that interrupts the story's otherwise heartwarming focus. Based on reactions of shock and the comment, "Uh-oh he wasn't supposed to find out," it is strongly implied that Yuyeon learns about his sister's association with Jaeyoon, creating a new, unexpected source of tension or comedic drama.
