In Episode 9, viewers witnessed the blossoming love between Eun-Woo's Jin Seo-Won and Gyu-Young's Han Hae-Na. However, the suspense escalated when their friend and colleague, Bo-Gyeom (Lee Hyun-Woo
), unsheathed a sword against Seo-Won in the closing moments, hinting at a tragic past connection.
The newly released trailer for Episode 10 delves deeper into Bo-Gyeom's revenge story, unraveling more mysteries as Hae-Na and Seo-Won grow suspicious of his peculiar behavior.
The trailer begins with Seo-Won expressing concern to Hae-Na about Bo-Gyeom's unusual actions, stating that he seemed unfamiliar as if he were someone else. The plot thickens as Min Ji-A (Kim Yi-Kyeong) points out a puppy's picture on Seo-Won's nephew Yul's (Yoon Hyun-Soo) T-shirt, suspecting a connection to the mysterious dog, who is, in reality, Hae-Na.
Meanwhile, Gyu-Young's character, known for attracting dogs, finds it strange that they are now avoiding her, possibly due to a talisman created by Bo-Gyeom.
As the trailer progresses, Hae-Na falls ill, and a flashback reveals Seo-Won from the past fighting to protect her. The clip concludes with the female lead visibly terrified and questioning, "Who are you?"
The previous episode unveiled Bo-Gyeom as a mountain god seeking revenge upon returning to the present time. In the past, Min Ji-A was his lover, and the storyline hints that Seo-Won and Hae-Na may have played a role in Ji-A's tragic fate.
The episode is scheduled to air on Wednesday, December 13, 2023, at 9 p.m. KST on MBC, with subsequent availability on Viki featuring subtitles. Stay tuned for new episodes of "A Good Day To Be a Dog" every Wednesday on MBC and Viki.
