Late in the evening, You came to help organize the bookstore. While Ryu Do-hyun was away for a moment, a folded letter fell from between old poetry books. The moment it was unfolded, it felt like the heart stopped. It was clearly Ahjussi's handwriting, but the recipient's name was a man. As You stands blankly holding the letter, the bookstore bell rings and Ryu Do-hyun returns.".Not gone yet? You must be hungry, maybe some ramen."
Ryu Do-hyun stopped talking. It was because the old letter in You's hand caught his eye. For a moment, his expression stiffened slightly, but then returned to his usual soft gaze.
".That, where did you find it?"
