For generations, a superpower has been passed down the maternal line in Bong-soon's family. But for 27 years, she has always tried to keep it hidden.
As Min-hyuk spends the day shopping and playing, Bong-soon is forced to follow him around. While at a park, they spot a suspicious man spying on them.
Bong-soon finds a painting in Min-hyuk's closet that seems out of place. The next day, the two visit the owner of the motorcycle they saw at the park.
Bong-soon struggles to control not just her power, but also her emotions. To make matters worse, Min-hyuk keeps giving her a hard time.
The criminal at large seems to be attacking only certain people. Concerned for Bong-soon's safety, Min-hyuk and Guk-doo clash over how to protect her.
Not able to trust one another overnight, Bong-soon, Min-hyuk and Guk-doo decide to play games instead, evoking the two men's competitive spirits.
Osung Group's shareholders get angry when Min-hyuk fails to show up on time to the meeting to discuss his qualifications as the next company leader.
Profilers suggest misogyny motivated the recent crimes. Bong-soon decides to put her dream of developing games second to catching the culprit.
Both Min-hyuk and Guk-doo arrive at the fight scene just before one of Baek Tak's men starts running toward Bong-soon with a dagger in hand.
Frustrated with police legalism, Guk-doo takes drastic measures. Bong-soon is preoccupied with catching the culprit herself, which worries Min-hyuk.
With the kidnapping case still unsolved and both Min-hyuk and Guk-doo asking to see her that night, Bong-soon finds her life is full of dilemmas.
Guk-doo's police team keeps hitting roadblocks while chasing down their suspect. Bong-soon senses something is off from Kyung-shim's text messages.
Replaying the video of Kyung-shim, Bong-soon hears a strange background noise. Following his hunch, Guk-doo decides to check out the junkyard again.
When Bong-soon doesn't come home late into the night, her dad gets worried. Guk-doo is conflicted over what to include on Kyung-shim's case report.
With the case unresolved, Guk-doo's team visits Min-hyuk's company to gather clues. Guk-doo hears from Bong-soon the details of last night's events.
As Bong-soon prepares to launch her online game inspired by her own story, she no longer feels ashamed to be her "special" self offline as well.
