Chicken Nugget

Choi Min-ah visits her father's office and enters a strange machine, undergoing a transformation. Choi Sun-man and Ko Baek-joong panic to find an answer.

Sun-man and Baek-joong try to track down the man who delivered the machine. They soon learn about a scientist who may know about the machine's origins.

Baek-joong pleads with his ex for help to spot which nugget is Min-ah. Searching for another machine, Sun-man looks into the missing Dr. Yoo In-won.

After an arduous night, Baek-joong and Sun-man meet with Dr. Yoo's old lab assistant. Back in the office, they discover someone's been after their machine.

After Yoo Tae-man steals the machine, he inadvertently brings back a long-lost figure. Baek-joong and Sun-man meet the two men, but with a cautious guard.

Baek-joong and Sun-man learn about Tae-man and Dr. Yoo's histories with the machines — and how one eventually arrived at More than Machines.

Despite pleas to bring Min-ah back, Dr. Yoo imprisons Sun-man and Baek-joong. Baekjung discovers his missing machine through Baek-joong's viral video.

Baekjung and his group set out to find their long-lost machine — discovering Sun-man and Baek-joong confronting Dr. Yoo and Tae-man.

Despite Baekjung's offer to help, a brawl erupts in the warehouse — until a proposal to bring back Min-ah deeply troubles Sun-man and Baek-joong.

Following Baekjung's departure, Baek-joong and Sun-man endure a decades-long wait. Upon Baekjung's return, he offers a tough decision about Min-ah's fate.
