The title suggests that during Kim Soo-hyun’s military service, he wrote a letter saying “I love you” to a romantic partner who is not Kim Sae-ron. This implies a relationship or affection he expressed for someone else through a letter during that time.

Actor Kim Soo-hyun has revealed the contents of the letters he sent to his girlfriend during his military service. The recipient of these letters is not the late Kim Sae-ron but another known partner, which serves as a rebuttal to various controversies surrounding Kim Soo-hyun’s relationship with the deceased. Kim Soo-hyun’s legal representative, Attorney Koh Sang-rok of law firm Feel, shared on his YouTube channel bulletin on the 30th that “the actor had an actual relationship from 2016 to the spring of 2019” and stated, “Throughout his military service, he regularly called his girlfriend whenever he had time and wrote about his feelings for her every day.”
