BY2 sisters, Miko and Yumi, have undergone a transformation not only in their names but also in the public's perception of them. From being the popular duo behind hits like "爱丫爱丫" and "有点甜," they have seemingly faded into obscurity since changing their names to Sun Huan and Sun Yu.

The decision to change their names was announced by BY2 in February 2019, marking a new chapter for the sisters as they left Sea Butterfly Music and established their own work studio. The name change was seen as a way for them to start anew.

However, this move has not been well-received by fans and netizens alike. Many feel that the new names, Sun Huan and Sun Yu, are too ordinary and lack the charm that made BY2 stand out. In the entertainment industry where stage names play a significant role in shaping one's career trajectory, it is crucial for artists to choose a name that resonates with audiences.

But what sparked curiosity among fans was not just the name change but also rumors surrounding BY2's relationship with King Force (王力宏). After Lee Lian Jye (李靓蕾) divorced King Force, she revealed some intriguing information about BY2's connection to him. Several marketing accounts even published screenshots of alleged messages between BY2 members on chat apps flirting with King Force.

In response to these claims, BY2 quickly reported these instances to authorities while Lee Lian Jye jokingly replied with an emoji representing seeking truth from facts. Recently though, there were updates regarding Lee Lian Jye vs King Force case; due to her inability provide evidence of infidelity or any concrete evidence linking BY2 with King Force’s alleged extramarital affairs—both parties were ordered by court judgment as guilty of contempt against law courts respectively.

Despite all this drama surrounding them both on personal matters as well as professional choices—BY2 continues its journey through uncharted territory under their new identities: Sun Huan & YuYu - formerly known as Miko & Yumi from pop sensation group By²!
