At least once a year, the world of K-dramas produces a compelling time-slip series that takes off on streaming platforms, sparking water cooler discourse over what happens next. This has included past hits like Twinkling Watermelon and Lovely Runner, or even recently this year with The Judge Returns. A common thread running between many of these is just how often they are available to stream on Rakuten Viki’s platform, and its latest series to hit the genre has been its new exclusive Dive Into You, of which Viki is also a coproducer alongside Dexter Pictures and Amuse Entertainment

Dive Into You combines familiar faces among its talent as actress Yoon Ha-na (Bona) and her judo champion brother, Ha-ru (Jang Se-hyuk), desperately try to prevent the horrific incident that claimed the life of their friend, Jung Woo-jae (Park Seo-ham). Woo-jae and Ha-na’s mutual feelings drive Ha-na to change the past, while Ha-ru joins her, incidentally letting his own life be drastically altered, while his own romantic prospects dwindle. Their treasured camcorder with memories of the past turns out to be the key to time travel, but with the added quirk of often having the Yoon siblings exchange lives, while multiple suspects surface as the vengeful stalker out to ruin their lives.
To explore the challenges of keeping a saturated genre fresh, ScreenRant interviewed director So Jae-hyun ahead of its premiere to address burning questions about its production, influences, and previous projects which led to this point. The director broke down the tricks and tropes that went into making Dive Into You, as the series culminates in its finale this weekend. For those who’ve been following along, it’s set up to be a high-stakes, cathartic finale in which futures have already been sacrificed and its real antagonist having revealed his true colors. But for those just discovering it now, this will easily be the perfect chance for a delightful, intriguing weekend binge.
Dive Into You Director Breaks Down How To Keep A Crowded Genre Fresh
ScreenRant: Body-swap and time-slip dramas have existed before, but not quite so drastically in the case of Dive Into You with its siblings experiencing both ends of the swap. What are the challenges of directing actors who have had to essentially embody their opposite cast member’s traits, and building a scene around that?
So Jae-hyun: It was hardest to capture the emotional arc of the other character, rather than just imitating their speech pattern. Even skilled actors were confused early on, so we aligned aspects like gait, gaze, and gestures with both actors before shooting. We also put effort into angles and lighting so that subtle traces of the original character could be felt, even though the bodies were swapped.

ScreenRant: Given the enormous catalog of hits across both subgenres of rom-com and fantasy, did you take particular influence from any contemporary hits like Mr. Queen, Lovely Runner, Moon Lovers, or A Time Called You?
So Jae-hyun: I really enjoyed all the titles you mentioned. Rather than referencing a specific work, I focused on the fast pacing and clear emotional shifts that viewers love these days. The fantasy setting is just a backdrop; in the end, what moves hearts is the genuine emotions and relationships between the characters.

So Jae-hyun: Time travel becomes boring if the explanations get too lengthy, so we removed all complex timeline theories. We focused purely on intuitive cause and effect—’how do my past actions affect the present?’—so that viewers can easily go along with the flow.

For the most part, director So Jae-hyun explores just that with the show’s time travel dynamics. Much like Sun-jae’s wristwatch in Lovely Runner, the camcorder in Dive Into You gets a lengthy exploration of what triggers the Yoon siblings to go back in time and swap bodies, such as falling into a body of water together with the device on their person, with each recording capturing a point in the past they can only alter once.
Dive Into You avoids getting too much into the sci-fi realm with this gimmick, which is a typical choice made in time slip K-dramas, focusing more on romance but with a fantasy thriller twist. But with each chance spent, Ha-na and Ha-ru’s lives grow drastically different often as the result of different choices made after body swaps, as do the lives of Woo-jae and even Ha-ru’s love interest, Son Ye-rang (Moon Seung-you).
Exploring Past Work & Influences On Dive Into You’s Production
ScreenRant: Despite not appearing to be based on a particular webtoon or webnovel, increasingly large amounts of dramas appear to be based on them lately. Was this show’s production or concepts in any way influenced by stories from either medium?
So Jae-hyun: Although there is no original work, I drew a lot of inspiration from the fast pace and distinct characterization typical of webtoons and short-form content. To keep the progression from dragging, we incorporated the speedy strengths of webtoons and blended them smoothly with the drama’s deep narrative.

ScreenRant: You’ve explored intersecting crime, action, comedy, and even supernatural elements with past projects like Dear My Room, The Witch’s Diner, The Player 2: Master of Swindlers, and Memorist before Dive Into You, although you appear to be the sole main director listed for the show. Have your previous projects or production credits influenced your work up to this point?
So Jae-hyun: I have worked across really various genres, from warm slice-of-life pieces like Dear My Room, to fantasy like The Witch’s Diner, and thrillers/action like Memorist or The Player 2: Master of Swindlers. This work feels like a gift set combining all the genres I have done so far. It contains comedy, fantasy, and emotional storylines, and thanks to the know-how accumulated from my previous works, I was able to maintain balance well and direct smoothly.

ScreenRant: Do you have any easter eggs or fun surprises for fans who have seen your previous work?
So Jae-hyun: Of course I prepared them! I subtly included characters that fans who loved my previous works will recognize right away. It will be very fun to watch while thinking, “Huh? Why is this somehow familiar?”

Familiar faces so far have included Ha Do-kwon who previously worked with the director on The Witch’s Diner, as well as other talent known for unrelated but similarly beloved recent works like Bon Appétit, Your Majesty with Moon Seung-you, or Hometown Cha-Cha-Cha’s Kang Hyung-suk. But as recently teased, former cast members of The Player 2 are set for a cameo in Dive Into You’s finale, with Krystal Jung, Lee Si-eon, and Tae Won-seok reportedly making an appearance.

ScreenRant: Your name has been attached to many all-time great productions too numerous to list here beyond quick highlights like Gyeongseong Creature, Castaway Diva, and Celebrity. You’ve also assembled an impressive cast for Dive Into You with fantastic credits to each of their names from even just the past couple of years. What pressures come with leading such a fascinating new production releasing to a global audience with an increasingly voracious appetite for K-dramas?
So Jae-hyun: The pressure is huge because expectations for K-dramas have risen globally! However, since veteran staff and great actors supported me, I was able to film with a pleasant sense of tension. I made it with confidence.

ScreenRant: The subtleties of a body-swap performance can feel not too different on the screen than live on the stage. With that in mind, beyond body language changes, what subtleties go into the scene blocking of Bona and Jang Se-hyuk that might bypass the average viewer’s attention?
So Jae-hyun: I paid a lot of attention to movement details like eye level, distance between characters, and position within the frame, not just tone of voice. Even without consciously trying, when you look at the screen, you will unconsciously feel that the souls have been swapped.

ScreenRant: You’ve worked on productions across varying tones and vibes for years now, with Dive Into You’s premise seeming relatively warmer aside from the likely developments surrounding Yun Ha-na (in Ha-ru’s body) with Jung U-jae’s story likely steering into slightly sadder territory. Would you say there’s a good deal of tonal variety in the show overall, as a tease for fans checking it out?
So Jae-Hyun: Yes, that’s right. The tone is truly colorful! It starts as a delightful and exciting body-swap comedy, and as it progresses, the hidden past narrative unfolds, becoming nostalgic and touching. It includes everything from laughter to emotion.

The dynamic of body-swapping characters in live-action can be trickier than previously conveyed in animation form like Your Name. Body language is key, characters suddenly need to adjust to height differences and hair length, and even wardrobe preferences become immediately apparent, with Jang Se-hyuk turning his screen time with Ha-na’s soul in his body into a four-course comedy meal. But Bona’s performance, from her deep well of feelings being unlocked by the emotional anchor of Park Seo-ham’s work, to the sudden immense martial arts proficiency of her brother trapped in her body, is a true sight to behold in this series, as it comes to a close this weekend.
Dive Into You airs its finale episodes on Saturday, October 31, and Sunday, November 1, 2026, streaming exclusively on Rakuten Viki.
