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 BY2, they are now known as Sun Huan and Sun Yu. This change has sparked curiosity among fans and critics alike, who wonder what led to this metamorphosis.

In February 2019, BY2 announced that they would be changing their stage names after their contract with their previous company had expired. The sisters went on to establish their own work studio, marking a new beginning for them in the entertainment industry.

However, not everyone is pleased with their new monikers. Many netizens feel that the names "Sun Huan" and "Sun Yu" lack the charm of BY2's original name. In an industry where names play a significant role in shaping one's career trajectory, it seems that BY2 may have taken a step back by changing theirs.

But what about By2's connection to Wang Likun? It is no secret that Wang Likun was once married to Liang Leilei (also known as Sandy Liang), who had previously been linked romantically with Wang Likun before her marriage ended abruptly due to his infidelity allegations involving pop starlet By2.

Rumors circulated online claiming By2 had sent flirtatious messages to Wang Likun on social media platforms before she reported these claims to authorities upon discovering such rumors circulating online against her band members' reputation amid news surrounding Liang Leilei & King Kong’s divorce case which involved both women - allegedly sharing intimate photos together from years ago while discussing how he could help get more attention for her music career under his management at Universal Music Group Asia Pacific division (UMGAP).

Following an investigation into these claims by police officers assigned specifically for handling cases related directly or indirectly involving celebrities (due mainly due high-profile nature of incidents happening within close proximity), officials found insufficient evidence proving any wrongdoing committed by either party: namely either side failed show concrete proof supporting assertions made against each other leading ultimately decision-makers reaching conclusion stating there wasn't enough reason warranting further action beyond just having legal proceedings initiated without going forward through full trial process itself becoming stalemate situation between parties concerned hereafter referred simply 'the dispute'.
