Sometimes the sparks on reality TV don’t fade when the cameras stop rolling. Lee Gwan Hee and Yu Si Eun, who first crossed paths on “Single’s Inferno 3,” have confirmed they’re a couple — and the story of how they got here is genuinely sweet.
Reports on July 29 revealed the two have actually been dating since December last year, quietly building their relationship long before going public. According to the report, they stayed in touch after filming wrapped, and what started as a comfortable friendship slowly turned into something deeper.
Rather than making a big splashy announcement, the couple chose to share the news themselves — posting matching messages on Instagram alongside a photo together. Their note read like a heartfelt letter to fans, thanking everyone for their warm interest and asking for continued support as they grow their relationship.
