Recently, Phuong Ly and Chau Bui were suspected of having a conflict when the female singer of "Your Sun" posted a long post thanking all her teammates and crew for supporting the performance "Just pour in the Rain". However, Phuong Ly did not mention Chau Bui even though they were in the same group.
Phuong Ly's actions surprised many audiences. Because before that, both singers had never revealed their dissatisfaction or controversy in the program or in real life.

In the member selection of livestage 3, Phuong Ly frankly invited Chau Bui to her team with the meaningful saying: "When we get married, how will the media be? Our sisters have many things in common."
Phuong Ly's words reminded the audience of the rumored love affair between the female singer - Andree Right Hand and Chau Bui - Binz's lover, both of whom are famous rappers.
As expected, when they were on the same team at livestage 3, Phuong Ly and Chau Bui had an intimate interaction right on stage when performing the performance "So Nam". In real life, the two female singers also made an appointment to go to each other's homes to watch this performance air.
In livestage 4, the two continued to be on the same team. Chau Bui took on the task of coming up with the costume design idea for the performance "Not Me". On their personal pages, Phuong Ly and Chau Bui have interactions such as taking a group photo, filming muddy videos, humorous...
Phuong Ly's actions confused the audience. Many people speculate that the two "beautiful sisters" had a big conflict during the preparation for livestage 4. Especially when Binz's lover is no longer allowed to prepare costumes for the song "Just pour in the rain".
As for Chau Bui, the female singer updated the image in livestage 4 to her personal page with a simple status: "I don't know what else to say, Chau thanks the audience a lot! Because he gave Chau suggestions, encouraged, and told her about the things she was not good at, so that Chau could strive every day to improve herself. Chau will listen, will appreciate, what everyone has given him, with the most sincerity! Thank you to my sisters, friends, and audience for being by my side! ".

Contrary to the initial positive image, Chau Bui is increasingly controversial because of his unlucky expressions and actions. Especially in the recent episode, the fashionista's excessive celebration expressions when Bich Phuong's group lost and had to eliminate 3 members made the audience even less sympathetic.
When taking on the group's outfit in the performance "Not Not Me", Chau Bui also received a lot of criticism for only taking care of himself, while his teammates' outfits were poor and lacking investment.
