The second season of Mnet’s survival show BOYS II PLANET is already creating buzz—and at the center of it are former BIGHIT MUSIC trainees Lee Leo and Lee Sangwon. Their standout performance of ENHYPEN’s hit song "No Doubt" during the Star Level Test has taken the internet by storm, sparking a wave of fan excitement and social media chatter.
In a preview released on July 14, the duo shared their personal journey from being BIGHIT’s Trainee A members to aspiring idols aiming for a second shot at debut. Their tight vocals and undeniable chemistry left judges visibly impressed and fellow contestants wondering if the performance was pre-recorded—thanks to their rock-solid live singing.
Why Leo and Sangwon's BOYS II PLANET Performance Is Going Viral
Performing ENHYPEN’s “No Doubt,” Leo and Sangwon were evaluated under the show’s ranking system—ALL STAR, TWO STAR, ONE STAR, and NO STAR. Contestants who fail to earn a star face immediate elimination. However, with the buzz surrounding their audition and the reaction it received, elimination seems far from likely for this talented duo.
Their performance didn’t just highlight vocal prowess; it reflected years of shared training, brotherhood, and persistence. Audiences and judges alike were captivated, earning Leo and Sangwon praise across fan forums and social media platforms.
Who Are Leo and Sangwon?
- Leo (Lee Leo): 22-year-old Australian vocalist
- Sangwon (Lee Sang Won): 22-year-old South Korean vocalist
Both were once part of BIGHIT MUSIC’s highly anticipated project Trainee A, which aimed to debut a new boy group following the global success of BTS and TXT. Unfortunately, the project was officially disbanded in December 2022 before the group could debut.
Post-disbandment, the longtime friends—who have trained together for nearly eight years—signed with GRID Entertainment. They were initially announced to debut as a male duo under the name Leo & Sangwon. However, chasing a bigger dream, they opted to compete in BOYS II PLANET with the hope of finally debuting together on a bigger stage.
- Leo’s training duration: 3 years and 7 months

Following Trainee A’s closure, Leo briefly pursued solo activities, but his bond with Sangwon led them both to rejoin the idol race as a team.
What’s Next for Leo and Sangwon on BOYS II PLANET?
With their viral cover performance setting high expectations, fans are eager to see how far Leo and Sangwon will go in the competition. Their deep friendship, polished skills, and emotional backstory make them strong contenders—not just for the show, but for long-term success in the K-pop world.
