BY2 sisters, Miko and Yumi, have undergone a transformation not only in their names but also in their career trajectory. The once popular duo, known for hits like "爱丫爱丫" and "有点甜," has now become somewhat of an enigma with their new monikers, Sun Huan and Sun Yu. This change has sparked curiosity among fans and the public alike.

In 2019, BY2 announced that they would be changing their names after completing their contract with Haibao Music. The sisters went on to establish their own studio, marking a new beginning in their careers. Their decision to change names was seen as a bold move by many.

However, the reception of this name change has been mixed. While some see it as an opportunity for the sisters to start anew and shed off any negative associations from the past, others view it as a step backward. After all, an artist's name is often closely tied to their identity and can greatly impact their success or failure in the industry.

But what about BY2's connection to Wang Likun? In light of Liang Lei's recent revelations about her relationship with Wang Likun after his divorce from her daughter-in-law Li Shengyun (also known as Michelle Chen), there were rumors circulating that BY2 had some sort of involvement with Wang Likun too.

These allegations led BY2 to report these claims on social media platforms before taking legal action against those spreading such information. However, when asked for evidence regarding Wang Likun's infidelity during court proceedings related to Liang Lei v.s By2 case , she failed provide sufficient proof resulting in being held accountable for contemptuous behavior towards the court .
