In the latest episode of SBS‘s Uh, But Like, Seriously!, Billlie’s Tsuki hilariously called out her agency CEO, Yoon Jong Shin, for not promoting the group enough.

The girl group member appeared as a guest alongside OH MY GIRL’s Mimi and comedian Kim Ji Yu. During the episode, the cast discussed the topic of “the rotten lifeline of my life,” referring to someone or something that seemed reliable but ultimately did not provide the support expected. Tsuki surprised the MCs when she named Mystic Story CEO and producer Yoon Jong Shin.
Before explaining, Tsuki quickly clarified her affection for him, saying, “Producer Yoon Jong Shin, I love you.” She then explained why she felt disappointed.
Billlie was Mystic Story’s first girl group. So even in articles, we were introduced as ‘Yoon Jong Shin’s girl group.’

However, according to Tsuki, the group did not receive the level of promotion she had expected from him.
I said that because he didn’t promote us. Whether on broadcasts or on social media, he didn’t promote us at all.
— Tsuki
Her candid comment drew attention as Billlie has often been described by fans as an “underrated” girl group, despite receiving praise for their strong performances, unique concepts, and talented members.
That said, Tsuki’s dramatic transformation for this comeback didn’t even need Yoon Jong Shin—she promoted herself. Read more about it here:
