Early March 2014, it was confirmed that director Charlie Nguyen and actor Thai Hoa had already been in the making of the movie De Mai tinh's spin off with the title De Hoi tinh. This was the 6th collaboration after De Mai tinh (2010), Long Ruoi (2011), Cuoi ngay keo lo (2012), Bui doi Cho Lon (2013) and Teo Em (2013).

At the end of March 2014, the crew was still being in pre-production before starting to film, including set design and costume for the cast, beside, the cast had already had a meet up and rehearsed together. The movie started filming at the beginning of April and the process only took within 6 weeks.

The crew had a wrap party on May 22. Until November, despite full edited movie, they still decided to film more scenes in order to make a better ending. Thai Hoa claimed these final days of filming and changing the script in hurry caused him "depression", that he didn't even dare to watch the premiere.

Charlie chose actress Diem My for the character Thu Le, after 3 rounds of casting. He stated that this role "was supposedly portrayed by another actress whose figure is bigger" which caused him spending 3 days casting. However, Charlie claimed that she (Diem My) "is smart to absorb the character's personality" also "being creative in littlest details". As for Diem My, De Mai tinh is one of her favorite movies, she really admires Charlie Nguyen but "nervous and stressful" when she was filming with Thai Hoa.

Actress Thu Trang said that the scene where she took off her clothes to seduce Thai Hoa's character shocked her husband - actor Tien Luat, he also appeared during the filming of that scene and felt "annoyed" as he had witnessed that scene himself.

The official soundtrack of De Mai tinh is "Nhu mot loi hua" (Like A Promise) by singer Thao Trang, who had also performed "Angel In Me" - the OST of De Mai tinh. The song was released as online digital single on December 13, 2014 along with English version "Like A Promise". Both versions were composed by Phan Cong Thanh. The Vietnamese version was performed by Thao Trang in Toi toa sang show in December 20. Ngoc Lee from YAN News complimented the song "like a breeze in the movie" due to its soft melody.

The initial release date was supposed to be in November, 2014 however the official release date was December 12, 2014. The premiere was 2 days before the official release at box office in Ho Chi Minh City.

At the start of October 2014, first poster was revealed along with other promotions. The old title "De Hoi tinh" with the poster portraying the character Hoi in new style with pink dyed hair, a shade and a mustache. A source said before release, the movie title was switched from De Hoi tinh to De Mai tinh 2 for commercial purpose maybe.

Actor Thai Hoa had predicted that the movie was unable to get 100 billion Vietnam Dong profit, "but let's see", he said.

With new title, De Mai tinh 2 attracted 71,766 audiences and earned 5,7 billion Vietnam Dong in first day, defeated Teo Em's record with 4 billion Vietnam Dong 4 years ago. Two days later, the movie continuously earned 7,5 billion Vietnam Dong and 8 billion Vietnam Dong with 200,000 audiences in total, which made De Mai tinh 2 be the second highest grossing after The Vengeful Heart in 2014. In first week release, the movie eared 45 billion Vietnam Dong, until the second week marked in December 26, the total grossing was 70 billion Vietnam Dong. Early 2015, the movie broke all the records applying for both Vietnam movies and foreign movies since it earned 90 billion Vietnam Dong. Later, this record defeated by Fast and Furious 7.

CGV stated that the success of the movie came from entertainment purpose targeting with simple plot that anyone can understand.
