BY2 sisters, Miko and Yumi, have undergone a transformation not only in their names but also in their career trajectory. The duo, formerly known as BY2, has changed its name to Sun Huan and Sun Yu respectively. This change is more than just a superficial makeover; it reflects the sisters' decision to break free from their past and forge new paths.

The reason behind this name change is rooted in the expiration of their contract with their former company, Sea Butterfly Music. After parting ways with the label, BY2 established its own studio and decided to embark on a new journey under the monikers Sun Huan and Sun Yu.

However, this transition has not been without controversy. Many fans are still struggling to remember the sisters' new names after years of associating them with BY2. The importance of an artist's name cannot be overstated; it can significantly impact one's career prospects.

As for By2's relationship with Wang Likun (王力宏), there were rumors circulating that they had an intimate connection before his marriage ended in divorce. These allegations sparked heated discussions among netizens who shared screenshots of alleged flirtatious messages exchanged between By2 members on social media platforms.

When confronted about these claims by Liang Lei (李靓蕾), Wang Likun's ex-wife accused By2 members of making false accusations against her husband out of malice. The legal battle between Liang Lei and By2 led to charges being brought against both parties for disrespecting the court.

In conclusion, while BY2 may have changed its surname but maintained some level of familiarity through similar naming conventions for its members under different monikers – akin to tracing hidden patterns within ancient Chinese divination charts – much remains unclear about how these changes will affect future endeavors or whether they will manage to regain public recognition amidst ongoing controversies surrounding personal relationships involving prominent figures like Wang Likun or Liang Lei.
