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 their names to Sun Huan and Sun Yu respectively, forming the new group "Raining Sun". This move is seen by many as a fresh start for the sisters after they parted ways with their original record label.

The reason behind this change is attributed to the expiration of their contract with Sea Butterfly Music. After leaving the company, BY2 established its own studio and decided to rebrand themselves. Their decision to alter their names has sparked debate among fans and critics alike.

While some view this name change as an attempt to revive their careers, others are skeptical about its impact on their popularity. It's true that an artist's name plays a significant role in shaping public perception of them. In fact, it's common for celebrities to adopt stage names or modify existing ones throughout their careers.

However, what remains unclear is BY2's connection with Wang Likun (王力宏). Recent reports suggest that Liang Le (李靓蕾), Wang Likun's ex-wife accused BY2 of having an inappropriate relationship with him. These allegations were later refuted by BY2 who claimed they were false.

Despite these rumors surrounding her personal life and relationships within the industry, it seems that BY2 is focused on rebuilding her career under her new identity as Raining Sun. As she embarks on this journey towards re-establishing herself in the entertainment world without any baggage from past controversies or failed relationships – let us wish her all the best!
