The show ranked first in the TV-OTT integrated non-drama category popularity ranking for three consecutive weeks from March 18 – March 25 and ranked first in the overall TV-OTT non-drama category for two consecutive weeks on March 18 – March 22 announced by Good Data Corporation.

## Format

My Sibling's Romance is a story about several siblings hiding each other's identities and gathering in one house while looking for their respective lovers. The format of the program is the same as other entertainment programs, where young handsome men and women come together to depict romance, but by filling the cast with siblings, it also deals with the friendship and family love between siblings. It is also has the format of mystery drama, in which the participants should guess the identity of the other's blood relatives. The siblings who appear in My Sibling's Romance pretend not to know who their siblings are. This is the first dating reality show to feature siblings. The siblings variable was also highly involved in the romance process because the sibling became cupids or villains of each other's romance. One of the panelist BamBam said that My Sibling's Romance has a sitcom like feels because of each sibling's chemistry, also has some throbbing feels because it contains a family story other than the main romance feels.

## Production
### Concept and development

My Sibling's Romance was created by producer Lee Jin-ju (PD Lee) under JTBC. Lee had previously worked as an assistant director for various works with producer Na Yeong-seok at TvN, and created the TVING original series Transit Love after becoming independent. After moving from TVN to JTBC, she produced My Sibling's Romance, which is similar to her previous project, Transit Love. The investigation aspect of guessing whose sibling is whose is similar to Transit Love, but the contestants are family instead of ex-lovers.
In an interview, PD Lee shared that the team that worked on Transit Love gathered together and came up with several plans for their new show, but as they talked, they ended up coming back to the dating entertainment program style they excelled in. Lim Jeong-ah, the head of JTBC's entertainment production division, also agreed that My Sibling's Romance family concept could appeal to a wider audience. At the production presentation in January, PD Lee shared that she had the idea of making a dating program with siblings because her friend worried about their brother, who appeared on a dating program. She thought the worrying feelings for family could become the fun interesting part of the show.

### Filming

The first half of My Sibling's Romance was filmed in South Korea; from episode 10, they filmed in Singapore. During an interview, PD Lee mentioned that staff placed more than 100 cameras around the house in order to film the show. The production staff members also hid behind a one-way mirror to shoot the participants. The staff rarely faced the participants except during interviews or when setting the microphone.

### Casting

PD Lee said that the casting of My Sibling's Romance required real relatives, but public auditions weren't able to be held because the new production idea was supposed to not be known in advance. The staff contacted around 1500 people through Instagram direct messaging; after deciding that the person was attractive, they revealed the show's concept, but many of those contacted did not have an opposite-sex sibling. Difficulties also came with casting the parents, as they had to appear in the show as well. Because of that, the siblings were not recruited with representativeness of 'normal family fantasy' in mind, but more of finding attractive people to recruit.

## Reception
### Critical reception

Pop culture critic Jeong Deok-hyeon said, "Dating and siblings may feel disparate, but in fact, the drama genre has dealt with a lot of family love," and added, "It appears that a lot of effort was put into recruiting performers with relationships that viewers can empathize with." He continued, "However, I expect that things will not go smoothly in the future," adding, "The strong family love shown in the beginning may lead to deep emotional conflict in the second half."

### Participants

List of participants, showing birth year, MBTI, Occupations, and Notes :
| Name | Birth Year | MBTI | Occupation | Siblings | Introduction |
| Jae-hyung | 1994 | ENTJ | Accountant financial advisory headquarters (3rd year at Big4 accounting firm, South Korea - Mergers & Deals Advisory) | Park Se-seung's older brother | Intro letter When we were young, Jae-hyung and I always held hands. Even at a young age, I remember him comforting me when I was fighting with my friends and crying in bed because I was upset. He was such an adult and good kid. Then Jae-hyung went through puberty and he didn't pretend to know me even when I ran into him outside. He liked singing while screaming, so he ended up forming a band. When Jae-hyung sang "Bus Stop" (정류장) at the concert, saying it was a song he dedicated to our mother, I was so moved that I secretly shed tears. I was so heartbroken when Jae-hyung, who had been looking for romance on stage, began to compromise with reality and start studying. He is a person who, when he decides to do something, does his best to do it, so I could see how difficult it must have been while enduring that period. Even now, Jae-hyung still teases me by sending me unshaven selfies and acting cute, but he is a warm and wise person who knows how to take care of his people more than anyone else. What do you think about the kind of work that Jae-hyung do? |
| Se-seung | 1996 | ENFJ | Foreign management strategy consultant (Preparing for a job change) | Park Jae-hyung's younger sister | Intro letter Is there anyone who likes steamed bun? Se-seung had dimples as white and sharp as steamed buns fresh from a steamer. Unlike me, who just hated being bothered, Se-seung was a class president and a good student who studied hard. Even when she was a college student, she lived a fresh life, participating in various club activities and getting an overall A+ grade. In graduate school, I was very inspired by seeing her studying all night long, as if she felt inferior to the researchers around her. I look forward to the future of Se-seung, who creates her own life. |
| Yong-woo | 1990 | ENTJ, ENFJ | Aspiring Pilot (Have pilot certificate to study in U.S. for 1 year after graduating P.E from Korean college) 2nd place on Mister International Korea 2022 and 4th place on Mister Supranational 2023 | Lee Ju-yeon's older brother | Intro letter As a child, Yong-woo was a child who loved books. Even when he was having a hard time as a child, he consoled himself by reading books. I think from then on, he learned not to get too excited and to maintain a positive mindset. He is a kind and humorous person no matter the situation, so he has the charm of making people around him happy when he is with him. Yong-woo grew up to be a persistent adult who, if there is something he wants to do, makes a detailed plan and carries it out without wasting time. After being discharged from the military, he said he had found what he wanted to do and went to the United States to pursue a dream that had nothing to do with his college major, where he began difficult studies and eventually achieved that dream. I think Yong-woo's persistence and the dreams he dreams really match. What do you think about the kind of work that Yong-woo do? |
| Ju-yeon | 1999 | ESFJ | Enbrox product team | Lee Yong-woo's younger sister | Intro letter Ju-yeon was a child who listened well to people's stories and had good reactions from a young age. So, ever since she was young, she was always loved among friends. Although she had a lot of worries about her career path and had a hard time, Ju-yeon is now adapting to social life better than anyone else, and I believe that like her mother, who has always been a great career woman, she will also confidently accomplish anything she does. What do you think about the kind of work that Ju-yeon do? |
| Cheol-hyun | 1991 | ENTJ | Advertisement model (Active since 2017. Appears in iHub, Samsung washing machine commercials, Jannabi music videos and more) | Park Cho-a's younger brother | Intro letter Cheol-hyun, who had a unique appearance from a young age, had a good fashion sense and was very interested in decorating himself. It is said that Cheol-hyun, who has a lot of cuteness, walked around holding his mother's hand and everyone looked at him, thinking he was cute. Cheol-hyun experienced a variety of things in an unfamiliar environment and had a lot of hardships, but I think he was able to grow faster through that opportunity. I feel fortunate that Cheol-hyun, who looks cold but has a warmer and more tender heart than anyone else, has a job that allows him to express himself. I sincerely hope that he can overcome his hidden wounds and live as a free person. What do you think about the kind of work that Cheol-hyeon do? |
| Cho-a | 1989 | INFJ | Jubis diet consultant Former yoga instructor | Park Cheol-hyeon's older sister | Intro letter Cho-a is a person who is both sensitive and easy-going. She is very curious, so when she catches something while walking, she stands there staring and thinking deeply. From an early age, Cho-a had a strong sense of responsibility. When we were young and our house was being robbed, I remember that little girl wrapping her arms around me to protect me. Not long ago, I climbed a mountain with Cho-a. I remember the moment we reached the top, relying on each other, pushing our backs and holding our hands. We promised to always be on each other's side whenever we take on a new challenge. What do you think about the kind of work that Cho-a do? |
| Jung-sub | 1996 | ENTJ | Artificial intelligence researcher (Attending Ph.D. program at Seoul National University Researching Bioinformatics) | Lee Yun-ha's younger brother | Intro letter Jungsub inherited a scientific mind from his father and an artistic sense from his mother. Jungsub, who was like a healthy and strong teddy bear, joined a dance club when he was a high school student and had to study hard, and became famous as Little U-Know Yunho, making his father catch him by his neck. If a person became close to my sibling, wouldn't he show his hidden talents? |
| Yun-ha | 1989 | ESTP | Cellist (Graduated from Korea National University of Arts. Master's course at Yale University in the United States.) | Lee Jung-sub's older sister | Intro letter Ever since she was young, Yun-ha was a sweetheart who always melted the hearts of her family with her pretty smile. She is a strong-willed person who endured the lonely life of studying abroad in front of her career and even won a scholarship with excellent grades. Although she does things that only she can do if she is more sensitive than anyone else, in real life she is surprisingly simple and cool, and has a variety of charms. Yun-ha is a person with a great desire to grow. Since she was young, there were times when she looked like a fool for being honest and simple and running with only one dream in mind, but I think that's what made Yun-ha who she is today. I hope that this friend's path will continue to be accompanied by brilliant melodies. Clap clap clap. What do you think about the kind of work that Yun-ha do? |
| Yun-jae | 1994 | ENTJ | Operate a restaurant | Kim Ji-won's older brother | |
| Ji-won | 1995 | ENFJ | Entertainment A&R team leader | Kim Yun-jae's younger sister | |
