After nearly 5 months of temporarily leaving social networks, Hai Dang Doo officially returned to the music race with the MV "Ngo Dong". The song was self-composed by the male singer, inspired by his experiences and the time he contemplated himself.
Sleeping in Winter" is a ballad filled with many thoughts of Hai Dang Doo. During his temporary absence from artistic activities, the male singer said he had time to return to his hometown, spending about a month writing music.
This period also caused many of Hai Dang Doo's music plans to be temporarily suspended. He once planned to participate in a music program, make new products and collaborate with other artists but decided to put it aside to spend time for himself.
According to Hai Dang Doo, music has become a way for him to continue to dialogue with himself during the time he rarely appears in public. Therefore, "Ngo Dong" is not only a product marking his return but also reflecting the mood of the male singer after months of temporary silence.

After a period of absence, what moved Hai Dang Doo the most was realizing that the audience still paid attention to him. He believes that whether a part of the audience continues to accompany or chooses a path is a decision that needs to be respected.
Coming from the program "Hello Brother", Hai Dang Doo has more friends and colleagues in the entertainment industry. During the time he temporarily left artistic activities, some close people still silently cared and encouraged him.

The male singer said that he is quite hesitant to ask for help from friends and colleagues. However, the timely attention of those around him helps him have more motivation when preparing to return to music.
