Kim Jaejoong is preparing to debut a brand-new boy group.

On the 19th, iNKODE Entertainment announced the launch of INTHE X PROJECT, a public trainee reveal initiative introduced through the company's official social media channels.

The project, often referred to as "Kim Jaejoong's Kids," unveiled its first three trainees: Sen from Boys Planet 2, along with undisclosed trainees Sena and Hyunmin.

A total of 10 trainees will participate in the lineup. Additional members—including Boys Planet 2 contestants Masato, Sun Jiayang, and Feng Jinyu, plus four more undisclosed trainees—will be revealed sequentially.

INTHE X PROJECT marks Kim Jaejoong's first full-scale production of a boy-group debut, following his successful involvement in SAY MY NAME, signaling another fresh spark in the K-pop market.

According to the agency, "Starting with the trainee profile releases, we will roll out various promotions to spotlight each member's individuality and potential."
