The recap of Episode 3 of "Master of the House," titled "Achilles' Heel," unfolds with Kita proudly presenting her meticulously designed outfit to her photographers and close friends, Dom and Abel. Dom suggests an intriguing idea—utilizing Kita's maid, Bee, as the model to capture the essence of the attire. Bee gracefully steps into the role, striking poses that earn her praise from both Abel and Dom, much to Kita's chagrin. In a moment of petulance, Kita publicly humiliates Bee by insisting she change in front of the group.
Bee, feeling the sting of embarrassment, requests privacy in the bathroom, but Kita defiantly strips her down and orders Dom to snap a photo of Bee in her nude state. Abel, sensing Bee's distress, offers his jacket as a makeshift covering. Later, as Bee attends to Kita's dog in the midst of her duties, a call from her sister disrupts the calm. Her sister conveys the urgent need for more funds to cover their mother's medical treatment, prompting Bee to assure her sister to continue her studies while she considers finding additional work.
Just then, Kita storms into the room, furious at Bee for taking a personal call during work hours. She ruthlessly tasks Bee with completing the remaining outfits for her collection. Elsewhere, Yupin assigns Kaimook the task of tidying up a storage room, where she stumbles upon a butterfly meticulously preserved—a poignant reminder of Roongroj's proposal on a fateful night. Kaimook's mind drifts back to that evening, revisiting the moment she placed a deceased butterfly into Roongroj's collection amidst his marriage proposal.
Returning to the present, Kita prepares to depart for a nightclub party. Padcha informs her of Phupat's steadfast resolve to send her to France. The scene shifts to the vibrant club, where Kita mingles with her friends until Shutter's arrival piques her jealousy as he engages with another woman. Meanwhile, Shutter's girlfriend, Joke, who doubles as his driver, calls Bee to check on her. Joke invites Bee out, but Shutter's plans take an unexpected turn as he joins Kita. He subsequently asks Joke to chauffeur them home, where Kita and Shutter reconcile amidst passionate kisses in the backseat.
The following day, the Thevasatitpaisarn family convenes for the solemn reading of Roongroj's will, marking a poignant transition in their lives.
Krit reads aloud the bombshell revelation that Roongroj had bestowed a 10% share each in Theva Gems to Padcha and Araya. He further enlightens the gathered maids that Phupat had been designated a 30% stake, yet it is Mavin who inherited a commanding 45% of the company, named explicitly as Roongroj's heir apparent. The room falls into a state of disbelief as they learn that Kaimook, contrary to expectations, received nothing from Roongroj's vast wealth.
Phupat, unable to stomach the arrangement, flatly refuses to accept the will's provisions and declares his intention to challenge its legitimacy through investigation. While Araya and Mavin revel in their unexpected windfall, Phupat's sanity teeters on the edge of collapse.
Later that evening, Kaimook seeks out Phupat and Padcha, returning a cherished necklace belonging to Phupat's late mother. She opens up to Phupat about Roongroj's demise, revealing that Mavin was the last person seen with Roongroj before his untimely end. She alleges that Mavin had threatened her life and expresses her fear that he might have been responsible for Roongroj's murder. However, Phupat remains steadfast in his disbelief, citing Kaimook's lack of concrete evidence against Mavin. Kaimook vows to uncover proof that will implicate Mavin.
That same night, Kaimook finds solace in Bee's company as they sit outside the servant quarters, sharing drinks and comfort in Bee's humble abode. Their conversation drifts to the intricate collection Bee had been meticulously crafting for Kita. To Kaimook's astonishment, Bee reveals that her laptop contains footage captured by a camera mounted on Kita's dog's collar—footage from the night Roongroj passed away.
The following morning, Phupat faces a humiliating setback as Mavin bars him from entering his former office, informing him that he has been removed from the company's board of executives. Enraged but powerless, Phupat seethes in frustration. That night, Dom and Abel catch Bee sketching outfit designs for Kita, unaware that Kita has overheard their derogatory remarks about her. Heartbroken, Kita flees to Shutter, begging him to rescue her from her tumultuous reality.
Shutter earnestly begged Kita for some time, envisioning a journey to New York together. However, Kita stormed off to her studio, fiercely thrusting her fingers into the sewing machine as a brutal lesson for Bee. Bee, startled and panicking, fled outside and fortuitously encountered Joke. Upon seeing Bee's severe injury, Joke quickly rushed her to the hospital for treatment, her hand bleeding uncontrollably.
The next evening, Mavin gathered friends and family to celebrate his appointment as the president of Theva Gems. On the eve of the party, Mavin chanced upon Shutter, and they embraced tightly, with Mavin apologizing for not being there for his estranged son for so many years. Meanwhile, Kita summoned Shutter to meet her at her studio.
At the party, Kaimook resumed her duties, serving drinks as a maid, while Araya plotted to embarrass her publicly. Elsewhere, Bee cleverly unleashed Kita's beloved dog, sending it racing towards the studio where Kita was entangled in a passionate embrace with her cousin, Shutter.
As the party reached its climax, Mavin astounded everyone with a dazzling diamond rain, while Phupat took the stage to deliver a speech celebrating his younger brother's success. However, just at this pivotal moment, a video exposing the intimate moments between Shutter and Kita flashed across the big screen, causing Araya to faint on the spot. Mavin desperately tried to stop the video, while Phupat dashed to the studio and witnessed the incriminating scene between Kita and Shutter with his own eyes. Enraged, Phupat attacked Shutter with punches and kicks until Padcha intervened, allowing Shutter to escape.
Mavin found Shutter outside, scolding him for ruining his promising future as the president of Theva Gems. Facing his father's accusations, Shutter countered that Mavin should be grateful to him, as he had concealed the surveillance footage of Mavin killing Roongroj. Meanwhile, in Shutter's bedroom, Kaimook unexpectedly discovered the crucial tape. Shutter hastily returned to his room to search for the disc containing the video but found it missing, leaving him panicked. Fury-filled, he drove off, with Mavin sending Tian to chase after him.
Elsewhere, when Kita confessed her love for Shutter to her parents, Padcha was filled with shock and disgust. The episode concludes with a thrilling scene of Shutter being chased relentlessly by a motorcyclist on the street. The motorcyclist blocked Shutter's car, daring him to get out. The motorcyclist then subjected Shutter to a brutal beating, ultimately abandoning him in the middle of the road, barely conscious.
