Are Joo-young and Jae-jin From Single’s Inferno Still Together?

Kim Jae-jin left the most memorable impression the moment he walked into the secluded island for Netflix’s ‘Single’s Inferno’ season 5, owing to his strolling gait. That’s how he ended up earning the popularity vote within hours, enabling him to immediately set off to Paradise with the woman of his choosing as the intense 9-day experience begins. He had no idea at the time that another individual – Lee Joo-Young – would end up being the one he would ultimately fall head over heels for, making their romance one for the books.

Lee Joo-Young and Kim Jae-Jin Clicked on a Deeply Personal Level

While Kim Jae-Jin’s first date was with the lovable Ham Ye-jin, they didn’t really connect on an intimate or romantic level despite having a good time getting to know one another. Since their feelings were mutual, they were able to pursue different connections upon returning to Inferno, and that’s where everything changed for the former during a game of volleyball. He and Lee Joo-Young were paired by pure chance, but his genuine care for her safety and his gameplay in hopes of winning made her feel sparks and develop a curiosity.

Therefore, the moment Joo-Young had the opportunity to choose a Paradise date, she didn’t hesitate to pick Jae-Jin even though Youn Hyun-jae had also started expressing an interest in her. Neither of them had any idea that this date would set the tone for them for the rest of the season, as the pair naturally meshed well together, understanding each other’s quirks, humor, and limits. The conversation between them also flowed easily and flirtatiously, with a comfort level between them even though it was the first time they were talking alone.

Things could have wavered between them when game-changer Lee Ha-eun chose Jae-jin for a Paradise date or when Joo-Young selected Hyun-jae to get to know him better. However, while the former could mostly only think of his prior date and even clicked a photo of a vase-less flower setting for her, knowing she is an artist, the latter also returned with clear intentions. Their conversations in Inferno, their quietly romantic second Paradise date, and their openness with one another regarding what they desired ensured that they left the experiment together.

Lee Joo-Young and Kim Jae-Jin Are Still Getting to Know One Anothr

When it was time for the contestants to make their final decision, Joo-Young knew without any hesitation that she would go for Jae-Jin. She appreciated Hyun-jae, cared for him, enjoyed his company, and was grateful for his affection at every step, but she felt a deeper bond with Jae-Jin. The chemistry between them was natural from the beginning, and, more importantly, they both felt butterflies while also feeling at ease in each other’s presence. Even if they didn’t have anything to talk about, they still sought each other out.

Therefore, of course, when Joo-Young and Jae-Jin left the gates of Inferno laughing at inside jokes while hand in hand, it felt as if they would definitely be able to translate their bond to the real world. From what we can tell, it doesn’t appear as if they have labeled their connection as of writing, but they are definitely still getting to know one another and building on what they had formed in Inferno. In fact, with both of them being artists, they have openly attended each other’s exhibitions as well as performances, and it appears as if they have even introduced one another to their friend groups to really mesh their lives. With the spark between them still glimmering, we are rooting for their romance to become something even bigger and ultimately last forever.

Lee Joo-Young is Focused on Furthering Her Business, While Kim Jae-Jin is Making Strides as a Choreographer

As a Furniture Design graduate with an innate interest in carvings, flower vases, textile art, wood furniture, and much more, Joo-Young is a proud artist today. She owns and operates a brand called Queenchi and is a YouTube influencer encouraging others to dabble in her craft in hopes of inspiring the next generation of professional artists. We should mention that apart from her own studio, the 25-year-old’s pieces have also featured in the 2024 Sangmyung University Graduate Exhibition, the 2024 Craft Trend Fair, and a space known as Kun’s Gallery in Daejeon in 2025.

From what we can tell, he has even started dabbling in modeling over the past couple of years, which has landed him some incredible opportunities, such as an ad campaign for Dior’s Sauvage perfume.
