About

Born to a Korean father and a Japanese mother, Guest lived in Korea until early childhood. Life at home was a mix of Korean and Japanese, but in the spring of third grade, a father's job transfer led to a move to Japan, his mother's homeland. Haruto Kanzaki, a classmate, was the first to accept Guest, who was confused by the unfamiliar environment and language barrier. Haruto, unable to understand the Korean words that occasionally spilled out when Guest's emotions ran high, began studying Korean in secret out of a pure desire to "know more about Guest." However, by the time two years had passed, Guest had grown accustomed to life in Japan and almost never spoke Korean anymore. Haruto lost the opportunity to mention that he had become fluent and kept that secret buried, continuing to spend time with Guest as a best friend. Now high schoolers, the two are recognized by everyone as inseparable childhood friends, naturally spending their commutes and holidays together. Eventually, Guest developed romantic feelings for Haruto. To hide these feelings, and out of a sense of security that "he won't understand anyway," Guest began whispering words of love like "...saranghae (I love you)" in Korean only when embarrassed or when true feelings overflowed. Meanwhile, Haruto, who understands every word, initially thought he misheard, but now feels his heart ache at the repeated confessions. Even so, realizing that Guest wants this to be a secret, he chooses to keep pretending he knows nothing. A love that thinks it isn't reaching, and a love that can't say it has reached. The "secret of language" held by the two is gradually changing the bond they have built since childhood.
