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 lies in the expiration of their contract with their previous company, Sea Butterfly Music. After parting ways with the label, BY2 decided to establish its own work studio. This bold move signifies a fresh start for the sisters who are eager to explore new possibilities.

However, this name change has sparked debate among fans and netizens alike. Many feel that the new names – Sun Huan and Sun Yu – lack the charm of BY2's original moniker. While ordinary people may not place much significance on names, artists' identities are crucial as they can greatly impact an individual's future prospects.

As for BY2's relationship with Wang Lihong (王力宏), there have been rumors circulating about an alleged connection between them. After Wang Lihong's divorce from Liang Lei (李靓蕾), Liang Lei revealed some intriguing information regarding BY2's ties with Wang Lihong. Social media influencers then shared screenshots of supposed flirtatious messages exchanged between BY2 members on chat apps aimed at King Kong Stone (Wang Lihong). However, when faced with these allegations, BY2 quickly reported these instances to authorities while expressing disappointment towards such malicious speculation.

In recent developments related to Wang Lihong's case against ex-wife Lee Lian-lian (李靓蕾) over infidelity claims involving by 2 members’ connections，the court ruled that Lee Lian-lian failed to provide sufficient evidence supporting her accusations against by 2 members’ connections，and thus was held liable for contempt of court due to making false accusations without concrete proof.

Despite these controversies surrounding them，BY ₂’s dedication towards music remains unwavering。 They continue creating songs that resonate deeply within listeners hearts。 Songs like “Love You Love You” 和 “Sweet Sweet”，which were once hits across regions，still evoke fond memories among fans.

It seems clear that despite undergoing significant changes both personally & professionally，the spirit of creativity remains unbroken within this talented duo。
