Behind-the-scenes footage of my boyfriend joining the army

Son Taiying jumped with excitement when she first read the script, thinking it was the role she had been waiting for. Son Tae Young played a sister-brother relationship with Jang Keun Suk in the film, and her real-life relationship was also a sister-brother relationship. However, after the filming of the film was completed, news came that she broke up with her boyfriend. Jang Keun Suk felt that the dull soldier hairstyle in the film did not match his past self, but it could better bring him into the emotions of the character. Danny An said that in order to play the role well, he deliberately "learned" from his friend Jang Hyuk, who gave him a lot of useful advice. Danny An practiced guitar very hard for more than three months for the role. During the filming of the film, Danny Ann's fans specially delivered takeaways to the entire crew. On the day of filming, in order to thank the staff for taking care of Danny Ann, 80 people were prepared with fruit, Gift packages for cookies, chocolates and other desserts. At the end of the film, the scene where the young people return to the military for a music performance took a total of 55 shots to complete, using three cameras and more than 100 extras.
