For the two women of SISTAR19, there is no passive way to love. They're fully committed to their emotions — slowly causing them to break down when the other person doesn't reciprocate.

"You're so casual, unlike me/ I'm burning intensely inside," Hyolyn croons in Korean in the opening verse of "NO MORE (MA BOY)." "For you, it's a simple curiosity/ Do you know it's everything for me?" Bora adds on the pre-chorus.

In this episode of Global Spin, SISTAR19 deliver a charismatic performance, elevated by their perfectly synced choreography and cheeky expressions.

SISTAR19 is a sub-group of the former Starship Entertainment K-pop quartet SISTAR, which disbanded in 2017. "NO MORE (MA BOY)," their first single in over a decade, dropped on Jan. 16 via KLAP Entertainment. It's an homage to their 2011 debut hit single, "Ma Boy," officially closing the chapter to the previous era of their career.

"We're more mature now, so the song's protagonists are, too," Hyolyn said in an interview with Rolling Stone. "We are all more sophisticated about handling the end of relationships than back then."
