"Mùa Đông nhớ anh" was composed by musician Nguyen Thanh Trung specifically for the runner-up of Bolero Idol 2019 Tô Ngọc Hà. The female singer shared that because they both have a similar musical sense, they can easily empathize. This made the musician trust her with his brainchild.

"The lyrics and melodies in Trung's works are very gentle, sincere and poetic. Most of the lyrics Trung wrote before composing the music were very simple verses. When a musician sent a song, he always said "if you like it, sing it" - To Ngoc Ha said.

The female singer added that every time she receives a song from a musician, she is both excited and worried about how to "speak" the musician's heart through the song. "Sometimes I also boldly "argue" to create a musical product that both the musician and I are most satisfied with" - singer To Ngoc Ha said.

"Winter Missing You" was made by To Ngoc Ha and the crew in nearly 3 months with elaborate scenes filmed at famous scenic spots and relics of Ninh Binh, Ha Nam such as: Trang An, Tam Chuc, Tam Coc, Van Long lagoon...

"The musician and I plan to introduce to the audience a musical product that is typical of that season each season. Each season has a different musical color" - Bolero Idol runner-up shared.

After winning the runner-up prize of Bolero Idol 2019, To Ngoc Ha chose Ho Chi Minh City to continue developing her singing career. The female singer has increasingly asserted herself on the professional music stage by promoting her ability to transform her voice with many genres of music.
