Exchange (; stylized as EXchange) also known as its Korean title literal meaning Transit Love, is an original South Korean dating reality show that airs every Wednesday on TVING, an OTT service in Korea. The series comprises four seasons. The first season aired in 2021, followed by the second season in 2022, the third season in 2023, and the fourth season in 2025.
The reality show is about ex-couples that have broken up because of various reasons, gather to reunite with an ex-lover or find a new person. The show featured ten single men and women, who are brought together to live for weeks at a time, go on dates and get to know each other without knowing who each other's X is. The participants of this show are not strangers, but rather pairs of ex-lovers. Four pairs of ex-couples live under one roof, some of whom are hoping to reunite with their former flames and some who are ready to find romance with the other participants.
The main focus of the production team was the chat room system where the participant can choose a person they like and send them a message for each round. In addition, text messages saying "X chose you" and "No" started with a point that X's existence should be differentiated.
For the season 1, Producer Park Sang-hyuk, who directed Strong Heart and Roommate on SBS and Island Musketeers, Seoul Mate, and Snail Hotel on Olive and tvN, is the head producer of Na Young-seok's division, and has produced everything from Grandpas Over Flowers to Youth Over Flowers, Three Meals a Day, Youn's Kitchen, etc.
Producer Lee Jin-ju, who was with Summer Vacation, took charge of directing for season 1 and season 2.
After Producer Lee Jin-ju moved to JTBC, Producer Kim In-ha took charge of the directing process for season 3 and season 4.
All production credits were adapted from TVING unless otherwise stated.
On December 15, 2021 TVING announced that it analyzed the total number of video on demand (VOD) users (UV) data for TVing users from December 2020 to December 2021 and selected a total of 15 contents (nine programs and six movies) by genre and preference. TVing's original "Exchange" topped weekly viewership for 10 consecutive weeks recorded to be the highest contribution to TVing's paid subscription, and was selected as 2021 entertainment show.
Although TVING did not reveal the exact number of views of "Exchange," it is undeniable that it is drawing high attention. It has become a hot topic in 43 videos including the full version of the show in a month since the first episode was released on June 26, surpassing 10.52 million, 4867 views. On top of that, the cast's Instagram and other social media are also booming. Not only is the number of YouTube subscribers increasing, but the number of Instagram followers has doubled, raising interest in individual cast members.
The biggest contributor to increasing the accessibility of TVING is definitely Exchange. It was promoted as a domestic original content that could captivate Korean viewers in the OTT market. Exchange captivated people in their 20s and 30s who are more active in watching TV, and it became an opportunity to promote TVING to the public and a representative program. As a result, TVING's paid subscribers and MAU (number of monthly users) rose sharply. In August, when EXchange was airing, MAU reached an all-time high of 3.87 million, and TVING usage rates soared in the third quarter. It was a result of the success that followed the syndrome of excessive immersion and proof of viewing on social media by people in their 20s and 30s.
