Oh that's cool that even if they debut already and not a part of treasure anymore that they can interact freely with their ygtb family(keita) I'm not sure about won though since I don't know how they know each other with hyunsuk and to think that they can visit their studio too..i love it//
That's Keita. An ex YG trainee who trained with Yoshi, Mashi, Sahi and Ruto along with 2 other ex-trainees Mahiro and Kotaro in YG Japan, and he also participated in YG Treasure Box where Treasure was formed.
No, Keita is Yoshi's younger brother. Because he was born in July 2001, it is different from Mashiho who was born in March 2001 when he was in Japan. Mashiho and Yoshi are friends. study in the same grade Because people born before April will study at the same level as those born after April in the previous year. But when living in Korea with a strict seniority system Causing a Mashiho born in a different year to Yoshi to call Yoshi hyung.
