### Summary
The engagement party shifts its focus from the central couple to the profound, often tumultuous bond between Yuna (Alicia) and her brother, Emperor Key. A deeply touching moment unfolds when Yuna reveals she deliberately chose to wear the cheap, "shameful" earrings Key was once tricked into buying for her over a set from Ares. Readers were incredibly moved by this gesture, interpreting it as a powerful, non-verbal declaration of sibling love that values the sentiment of his first-ever gift above all material worth. This act perfectly encapsulates their dynamic: they may bicker endlessly, but their loyalty is absolute. However, the chapter pivots from heartwarming to heartbreakingly comedic when Yuna, attempting to console her distraught brother, introduces him to a friend. The situation backfires spectacularly, delivering a "triple heartbreak" to the young emperor: not only is his sister marrying his idol, but his first crush is revealed to be the friend Yuna introduced—who is also three months pregnant. Fan reactions were a mix of tears for the sibling moment and uproarious laughter at Key's romantic devastation, with many expressing comedic pity for the "poor lil fanboy" while speculating this will pave the way for him to meet his destined "Fairy Queen."
