The romantic tension in tvN’s weekend K-drama ‘Potato Research Institute’ is set to escalate as Yoon Hee-jin (played by Jung Shin-hye) makes her entrance. The production team teased that in Episode 5, airing on the 15th, Yoon Hee-jin’s arrival at the guesthouse will bring major changes to the relationship between Kim Mi-kyung (Lee Sun-bin) and So Baek-ho (Kang Tae-oh).
In Episode 4, So Baek-ho maintained his decision not to revoke Kim Mi-kyung’s dismissal, creating an air of unease between them. Although Kim Mi-kyung was bewildered by his cold demeanor, So Baek-ho himself seemed unsettled by her struggles. Their intense eye contact left viewers eager to see where their relationship will head next.
In Episode 5, Kim Mi-kyung will carefully observe So Baek-ho’s house while disguised in military attire, preparing for Yoon Hee-jin’s influence. Yoon Hee-jin, who brings new energy to the guesthouse, will share a surprisingly close moment with So Baek-ho at her welcome party. Kim Mi-kyung’s jealousy and suspicion flare up as she watches So Baek-ho’s affectionate gestures toward Yoon Hee-jin.
The production team also hinted that Yoon Hee-jin’s presence will not only impact Kim Mi-kyung and So Baek-ho’s romance but will also affect the dynamics between Lee Ong-joo (Kim Ga-eun) and Kim Hwan-kyung (Shin Hyun-seung). “Episode 5 will introduce dramatic events that shake up the relationships among the guesthouse residents,” they shared.
Airing at 9:20 PM on weekends, ‘Potato Research Institute’ continues to intrigue viewers with its evolving romantic entanglements. With Yoon Hee-jin’s arrival sparking both disputes and unexpected developments, anticipation for the next episode remains high.
