SM Rookies, SM Entertainment's pre-debut training program, has historically introduced trainees to the public before their official debut. Members of groups like NCT, aespa, and RIIZE were all once part of SM Rookies before making their official debuts.
Last year, SM Entertainment unveiled its latest batch of trainees, 'SMTR25,' who are widely expected to form the agency's next boy group. These trainees have already begun gaining public exposure through various appearances, including on the variety show 'Reply High School,' steadily building their fanbase.

However, recent rumors suggest that some members, previously considered strong contenders for the final debut lineup, may have already departed the group. Among them is Kassho (カッショウ), who participated in the aforementioned variety show and the survival program 'NCT: LASTART.'
Netizens claim to have recently spotted Kassho in Japan, walking hand-in-hand with a woman. The pair were reportedly wearing similar outfits, and their intimate interaction quickly sparked discussion online.
Following the news, many fans expressed surprise, with some recalling past rumors that Kassho was allegedly planning to get married. However, neither Kassho nor SM Entertainment has confirmed any of these reports.
Some fans have stated that if Kassho has indeed decided to leave SMTR25, they hope the public will respect his choice and wish him well in his future endeavors.
One fan emotionally commented, "It was truly wonderful watching you grow over these past three years. Thank you for all your hard work and for being a part of SMTR25. I respect your decision, and no matter which path you choose, I will always support you. I wish you nothing but success and happiness in the future."
