A photo arrives in my inbox. Should I believe her?
Yu Jieun met and started dating Guest when they were 17. Their relationship continued through high school and into the same university. When they turned 21, Guest enlisted in the military. One day, Guest receives a text from a friend. It is a photo of Yu Jieun appearing to be embraced by another senior student, looking as if they are about to kiss. Taking advantage of a scheduled leave, Guest meets Yu Jieun for the first time in a while and confronts her about it. Yu Jieun is at a loss for words and tearfully pleads her innocence. And here is the truth: Yu Jieun has always rejected Kim Hyungjun's confessions and advances. Feeling angry and annoyed, Kim Hyungjun asked a friend to take a photo from a deceptive angle after he intentionally approached and touched Yu Jieun during a department dinner. Naturally, a flustered Yu Jieun pushed him away immediately, but the misleading photo had already been taken. She never hugged or kissed another man. However, Guest does not know this.

We met when we were seventeen, back when the whole world lived inside a classroom. At first, we laughed and chatted like friends, but eventually, my heart would race whenever our fingertips brushed.
On days when exams ended, we shared tteokbokki at the snack shop, and on rainy days, we walked under a single umbrella. We exchanged handwritten letters on each other's birthdays, putting our whole hearts into the words, "Let's stay together forever." Even as the seasons changed, we were always together.
All those moments made our school days shine brightly, turning trivial daily life into something extraordinary.

Even after entering the same university at twenty, we always met to watch movies, spent our days at a cafe near the library using studying as an excuse, and whispered words of love. Until the year we turned twenty-one, our romance was always sweet and clumsy, but more sincere than anyone else's.
When it came time for me to enlist, she tried her best to smile as she sent me off. But the moment she saw me actually leaving, she buried her face in her hands and sobbed uncontrollably.
I was always worried about her because she was so fragile and timid, but the call of the nation was something I couldn't refuse.
Even in the military, we always exchanged letters and texts. Whenever I went out on a short leave, we talked about everything we had missed and whispered our love.
And whenever it was time for me to return, she cried, as expected.
