Kim A-rin and Kook Dong-ho were the underdog couple ofSingle’s Inferno Season 4, and now theNetflixseries has come to an end, it’s natural to wonder whether they are dating now.
AlthoughSingle’s Inferno’slatest chapter has only just finished airing, filming took place back in June 2024. A lot can happen during that time, as evidenced by thecouples (or lack thereof) who are still together.

Much of the attention was on Season 4 cast membersYuk Jun-seo and Lee Si-an, especially after the latter struggled to work out her feelings (Jang Theo and Kim Jeong-su both chose Si-an too).
However, A-rin and Dong-ho quickly garnered positive attention from viewers at home for their authentic interactions and the fact that fate brought them together – but did this continue after theNetflix show?

Dong-hosharedthe same Netflix photo of him with A-rin, writing, “Although It was awkward at first in an unfamiliar environment, with the help of precious people I’ve met through a program called Singles inferno, I’ve made unforgettable memories.”
The pair are also both still following each other on Instagram. And if that weren’t enough, Netflix just shared a cast interview, where they both expressed their feelings for one another.
Dong-ho says, “Even when I was in Paradise with someone else or A-rin wasn’t with me, I couldn’t stop thinking about her. That’s how I knew she’d be my final choice.” A-rin, who’s sat beside him, replies, “I felt the same way.”
It didn’t take long for fans of the series to pick this up, with one sharing a screenshot of A-rin’s Insta post onReddit. “This makes me think they’re still dating,” they said.
Another agreed, “100% dating. Most of the Polaroid pictures in her post have Dong-ho. They were wearing the same ring this day and his answer to the heart flutter question the same day confirms it.
“It’s also the same day they both answered how they think it’s green light to share pictures everyday. Trying not to laugh and get caught. My new forever ship.”
“I hope they’re the first Singles Inferno couple to go long-term,” added a third, while a fourth chimed in, “A-rin literally liked Dong-ho’s post in less than two minutes of him posting.”
In the comments section of the cast reunion video, one wrote, “The end part where they talked about how much they missed each other when they were separated… they wouldn’t say that if they weren’t dating right? Right??”
Why fate may have brought them together
Another reason fans are shipping A-rin and Dong-ho is the fact that they have so much in common.
As they found out during their date in Paradise, they both live and work in the same neighborhoods, their parents live in the same area, and they both were born in the same month.
“We might have crossed paths,” says Dong-ho during their date. After their time together, A-rin says it got her thinking whether it was “fate.” Even theSingle’s Inferno hostswere shocked by their similarities, with Hanhae saying he has “goosebumps.”
When they coupled up in the Season 4 finale, the hosts reminded us of their similarities, with Dex saying, “It’d be cool if they got married.”
