Lee Gwan-hee of 'Single's Inferno 3' Confirms Relationship with Yu Si-eun

Lee Gwan-hee (이관희), a professional basketball player and a prominent figure from Netflix's dating reality show Single's Inferno 3, garnered significant attention for his interactions with multiple female contestants, earning him the nickname "King of the Sea" from many viewers. Although he ultimately paired with Choi Hye-seon (최혜선) on the show, their relationship did not develop further. However, Korean media reported today, June 29, that Lee is now officially dating Yu Si-eun (유시은), another contestant from the show. The couple subsequently released a joint statement on Instagram, openly confirming their relationship, a revelation that immediately sparked heated discussion.

According to an exclusive report by Korean media outlet Sports Chosun, Lee Gwan-hee and Yu Si-eun began dating in December 2023. Although they did not pair up on Single's Inferno 3—Lee chose Choi Hye-seon, and Yu chose Choi Min-woo (최민우)—they maintained contact after the show concluded, frequently meeting privately, and their feelings for each other gradually deepened.

In fact, Yu Si-eun was spotted at the KBL All-Star Game in 2024, cheering for Lee Gwan-hee, which led many netizens to speculate about their close relationship. As they spent more time together, their friendship evolved into a romantic relationship, with both supporting and accompanying each other. Korean media even captured images of the two on a date at an aquarium, which ultimately brought their relationship to light.

Addressing the dating news, Lee Gwan-hee and Yu Si-eun chose not to keep it private. Instead, they issued a joint statement on Instagram, officially announcing their relationship. They stated: "Hello everyone, we are Lee Gwan-hee and Yu Si-eun. Today, we want to personally share some happy news with you. With your continuous warm interest, we have been quietly getting to know each other, and we feel it's now time to personally share our feelings with you. In the future, we will cherish each other, support one another, and nurture this beautiful relationship together. We hope you will continue to give us your interest and warm blessings. Thank you."
