5th Gen Idol Gives His Sister Money…Just So She Can Spend It On A Rival Idol

If there were a “Best Brother of the Year” award, BOYNEXTDOOR‘s Taesan might be bringing it home in 2026!

He and two of his members, Woonhak and Jaehyun, appeared on the June 11 episode of Mini Pinggyego, a spin-off of the hit Korean YouTube talk show Pinggyego, created by Yoo Jae Suk. At one point during the chat, Taesan revealed that some of his hard-earned money has been going straight into another idol’s pockets, thanks to his little sister.

Taesan revealed that instead of using the funds for herself, his sister spends them on merch, albums, and birthday cafes for her favorite idol from a different group. To add insult to injury, her bias is from the same generation as BOYNEXTDOOR!

His sister even wanted to attend that idol’s concert…so Taesan paid for that too!

The clip quickly spread across social media, with some fans praising Taesan for being such a caring and generous older brother and others wanting to know who this mystery idol is.

I think I remember him saying he’s friends with some of the members too so you can narrow the guesses like that
