Single's Inferno star Lee Si-an spills all on her filming experience, from dealing with tough conditions and body-shaping secrets to her honest moment with Yoo Jun-seo on set.
Model Lee Si-an, who made a splash on Netflix's Single's Inferno 4, has opened up about her experience on the show, revealing behind-the-scenes moments and honest stories that fans couldn’t get enough of.
In a recent appearance on MBC’s Radio Star, Lee Si-an joined fellow guests Woo Hee-jin, Hwang Dong-joo, and OHMYGIRL’s Mimi for an exciting special segment. She introduced herself by saying, “I was an idol trainee but now I’m a model. I became the most popular contestant on Single's Inferno 4 and dream of becoming the second Dex.”

Life Before Single's Inferno
She revealed that she had been an idol trainee for about six years, saying, “I used to have two or even three schedules a day. I even did a brand advertisement shoot in LA. Normally, we would’ve shot in Yangyang, but I flew in business class,” which grabbed everyone’s attention.
She added, “When I appeared on Produce 48, I was closest to Kwon Eun-bi. At that time, people said I was like Park Na-rae and Jang Do-yeon,” explaining, “I was more like Do-yeon sunbaenim (senior).”
Tough Filming Conditions and Body-Shaping Secrets
Lee Si-an shared the difficult conditions she faced while filming, saying, “The environment wasn’t great. I brought 40 to 50 outfits and had to do my own hair and makeup. Even though we filmed for ten days, I changed clothes up to three times a day.”
She also confessed, “I wore a bikini for the first time. Since I had to look my best, I collected various accessories and body-shaping tools to enhance my appearance. I used shaping devices to help me look more toned.” Lee Si-an didn’t shy away from being real about the preparations and sacrifices she made to fit the show’s glamorous image.

The Viral Bed Scene with Yuk Jun-seo
One of the most talked-about moments from Single's Inferno 4 was the bed scene between Lee Si-an and Yuk Jun-seo. She said, “Everyone kept asking what we did under the blanket. We just held hands and slept.” Lee Si-an continued, “People were upset and said it was too provocative, but my mother told me that if I received criticism, it meant the show was doing well.”
Mimi then asked, “Are you two really dating?” to which Lee Si-an replied, “We are more like close brother and sister.” She further explained, “We contact each other often, eat together, and are really close. We care for each other and get along really well.”

Looking Ahead: Single’s Inferno 5
Single’s Inferno has become one of Netflix’s most popular dating reality shows, with each season receiving massive attention. After the success of Season 4, Netflix wasted no time announcing the next season. On the 5th of last month, Netflix shared a recruitment notice on Instagram: “We’re looking for the next stars of the world’s hottest hell, Single’s Inferno. Check out the Single’s Inferno 5 story highlight on Netflix’s profile now.”
The recruitment period for Single’s Inferno 5 is open until the 30th of this month, and fans are eagerly awaiting to see who will join the cast in the next season of this addictive dating drama.
