Lee Jin Kyu

Lee Jin Kyu (이진규) enters My Idol, My Debut through one of the more interesting routes in this cast lineup: not as a heavily overexposed idol star, but as part of the younger talent layer helping Boy to the Moon feel like a complete team rather than a two-person spotlight device. That matters in a project built around group chemistry as much as central leads.

According to the Soompi and Sports Donga casting reports, Lee Jin Kyu plays Kaden, one of the members completing Boy to the Moon around Han Jae Ha, Ethan, and Eun Ho. The role places him inside MBC Plus's broader experiment to turn fictional drama groups into real-world performance acts with music and stage activity beyond the show itself.

At this stage, the key reason to track him is momentum. Projects like this often become discovery vehicles, and Lee Jin Kyu is positioned inside one that was designed from the start to create fan attachment across both story and performance.
