### Summary
The contractual engagement between Yuna and Duke Ares kicks off with a disastrously comedic first "date," which is promptly crashed by Yuna's adoring younger brother, Emperor Key. The chapter descends into hilarious chaos as Key, a passionate Ares "fanboy," completely derails any attempt at romance, prioritizing a "bromance" with his hero over his sister's mission. Readers are roaring with laughter at Key’s oblivious "c\*ckblocking," as he unwittingly sabotages the couple's every move. Yuna’s plan to stage a cliché romantic outing at a dessert shop proves to be a spectacular failure, as the choice is so comically out of character that even her brother isn't fooled. The event is celebrated by fans as a cringe-worthy but endearing "mess," highlighting how Key knows his sister better than she gives him credit for. While most enjoy the family-centric humor, some readers express lingering confusion over the plot's logic, questioning why Yuna agreed to the engagement at all after proving her capabilities in the previous arc.
