Twist One: Who Was the Killer Really After?
After the twins save Woo Jae (Park Seo Ham) from debt collectors, the timeline shifts. He quits judo, vanishes from their lives and a different bodyguard accompanies Ha Na on award show night. Armed with knowledge of the coming attack, the twins set a trap: Ha Na stays away from the green room while Ha Ru watches for the attacker.
Then comes the shock. A figure in black with a helmet leaves a bouquet outside her door, and when Ha Ru chases and unmasks him, it is Woo Jae himself. Barely has Ha Na hugged him when the same stalker appears with a knife, and Woo Jae once again takes the blow meant for her. Even more chilling, the attacker keeps stabbing after realising he hit the wrong person.
The next episode explains why. The killer is not Ha Na’s stalker at all. He is Woo Jae’s old judo rival, who blames him for ending his career. The new question is how things change now that this rival has accidentally fallen for Ha Ru.


Funny Moment One: The Lottery Solution
Episode 3 clarifies how the time travel works. The camcorder holds videos dating back to the 2010s, and each jump takes the twins to the date of the next video in order. Using that logic, Ha Ru checks the date of the third video, searches for the winning lottery numbers on Saver (the show’s version of Naver) and buys dozens of tickets. Woo Jae’s debt disappears. The only flaw is that the twins forgot to buy a few tickets for themselves.
Funny Moment Two: Woo Jae Falls for the “Wrong” Person
Thanks to the soul swap, Ha Na must train in judo inside Ha Ru’s body so he can win the upcoming medal. Training up close leaves Woo Jae baffled, because his heart races around the person he believes is Ha Ru. Yet he keeps picturing Ha Na’s face, a hint that he senses something is off. It is the funniest thread so far, and it quietly proves where his true feelings lie.
Twist Two: Ha Ru’s Future Changes
Their meddling comes with a cost. During the fight with the goons, Ha Na, inside Ha Ru’s body, cannot do judo and falls, and a goon hits her knee. That injury returns during the competition against Woo Jae, so she loses the match. Two years later, in 2013, Ha Na tells Ha Ru that he has left judo, and he ends up working part-time at the family restaurant. Since the jumps follow the videos in order, the twins cannot simply pick their destination. Despite everything, Woo Jae still walks away from judo too.
What Comes Next?
The rule is clear: every rescue attempt rewrites something else. Will Ha Na lose her acting career as well? Can they stop Woo Jae from becoming a security guard?
