BOYNEXTDOOR member Taesan revealed he has been paying for his sister's purchases of albums, merch, and concert tickets for a rival fifth-generation K-Pop idol. The story came out during the June 11 episode of Mini Pinggyego.
Taesan appeared alongside members Woonhak and Jaehyun on the Yoo Jae Suk spin-off show. He explained that his sister uses the money he gives her on goods and birthday cafe events for her bias from another group in the same generation as BOYNEXTDOOR.
The idol even wanted to attend a concert, so Taesan covered those costs too. The clip quickly spread online, with fans calling him a generous brother while others tried to guess the mystery idol.
Social media users shared reactions ranging from praise for Taesan to curiosity about which group his sister supports. The full episode is available to watch on the show's platform.
