The Potato Lab Episode 4 brought a major shift in the dynamic between Kim Mi-kyung (Lee Sun-bin) and So Baek-ho (Kang Tae-oh). The tension between them reached new heights as they clashed over a difficult decision. Despite Mi-kyung’s desperate attempts to hold onto her position, Baek-ho remained firm in following company rules. However, something about the situation unsettled him, making him act in ways even he didn’t expect.
The episode ended with an unforgettable scene in the pouring rain. Mi-kyung struggles to protect valuable potato seeds from getting damaged, determined to do whatever it takes. Just as she lost her balance in the harsh weather, Baek-ho appeared. Their intense eye contact at that moment hinted at something deeper between them, leaving viewers eager to see what happens next.
Kim Mi-kyung Refuses to Give Up
Being laid off came as a shock to Mi-kyung. She couldn’t believe it was happening. Baek-ho, following strict company policies, told her that the research institute needed top experts, implying that she was no longer necessary. His blunt words hit her hard. However, she wasn’t someone to accept defeat so easily.
The next day, Mi-kyung confronted Baek-ho again, hoping for a second chance. She asked if there was any way to reverse the decision, but his response was cold. He made it clear that there was no turning back. She even tried negotiating—offering to resign before being fired or freeze her salary—but nothing worked. Accepting the harsh reality, she later ran into her ex-boyfriend, Park Ki-se (Lee Hak-joo), who offered to help her stay at the institute. Instead of relief, his words only made her feel worse.
A Tense Mistake Leads to an Unexpected Reaction
Meanwhile, at the research team’s regular meeting, an unexpected mistake caused chaos. Jang Seul-gi (Kim Ji-ah) accidentally sent a message criticizing Baek-ho in the team’s group chat. To prevent bigger trouble, Mi-kyung took Baek-ho’s phone and deleted the messages before he could see them. Although she succeeded, Baek-ho was deeply disappointed in her actions. Yet, despite his frustration, he couldn’t stop thinking about her.
Later that night, a storm hit. Mi-kyung rushes to the institute to protect the research materials. As she struggled to keep the plastic covering intact, the strong wind knocked her off balance. Just then, Baek-ho appeared. Soaked from the rain, he stood in front of her, and their eyes met. The moment was brief but powerful, revealing unspoken emotions between them.
The upcoming episode promises even more twists. The Potato Lab continues on the 15th at 9:20 PM KST.
