'Single's Inferno 3' Lee Kwan-hee and Yoo Si-eun Confirm They Are Dating

Two cast members from Netflix's Korean dating series "Single's Inferno 3" have gone public with their relationship. Lee Kwan-hee and Yoo Si-eun are officially dating, according to a personal message Yoo shared on her social media account on July 29.

"Hello, this is Lee Kwan-hee and Yoo Si-eun," the message began. "Today, we wanted to share some happy news about the two of us directly with you."

Yoo wrote that the couple had been quietly getting to know each other while receiving warm interest from fans, and now felt ready to speak openly. "We plan to care for each other, cheer each other on, and grow a beautiful love together," she added. "We ask for your continued interest and warm support. Thank you."

The pair appeared together on "Single's Inferno 3," a Netflix original dating competition that isolates single Korean contestants on a remote island as they pair off in search of romance. During the show's run, Lee and Yoo were matched with other cast members on screen. Their real-life relationship developed after filming ended.

Netflix's "Single's Inferno" franchise has become one of the platform's most-watched Korean unscripted series since its 2021 launch, drawing global audiences and turning several of its cast members into social media stars. Post-show couples have become part of the show's cultural pull, with fans closely tracking which pairings continue offscreen.

For Lee and Yoo, the announcement marks the end of months of speculation and a shift from television storyline to a public relationship on their own terms.
