### Summary
Building on the established theme of comedic sexual frustration, this chapter details Suh Yoonseul's failed attempt to seduce Kang Jun. Driven by his new, unabashedly flirtatious personality, Yoonseul devises a plan, lying to Jun about a family meeting with the secret intention of taking him home to consummate their relationship. His internal monologue reveals intensely "lewd" and "horny" thoughts, a stark reversal of his past self that confirms to readers he has "fallen harder." However, the seductive scheme is hilariously thwarted by his own siblings. Having been paid by Yoonseul to vacate the house, they instead take his money and remain home, a maneuver fans have overwhelmingly dubbed a classic "cockblock." This comedic betrayal is celebrated by the audience, who find the siblings' antics realistic and amusing. The chapter leaves Yoonseul's plan in ruins and his frustration palpable, while the "adorable" and "innocent" Jun remains completely oblivious to the foiled plot, successfully escalating the couple's palpable tension through lighthearted conflict.
