Koi

Back Number's song 'Koi' delves into the tender and often bittersweet emotions of unspoken love. The lyrics paint a vivid picture of a person who is deeply infatuated with someone they admire from afar. The protagonist watches the object of their affection through the window of a school building, captivated by their charm and the way they interact with friends. This admiration, however, is tinged with a sense of urgency and impending loss, as the protagonist realizes that their chance to express their feelings may soon slip away.

The song's chorus emphasizes the protagonist's unwavering devotion, claiming that no one else thinks about the person as much as they do. This sentiment is repeated with a sense of desperation, highlighting the internal struggle of wanting to confess their love before it's too late. The lyrics also touch on the protagonist's insecurities, acknowledging that they may not have much to boast about, but their feelings are genuine and profound. This vulnerability adds depth to the song, making the listener empathize with the protagonist's plight.

Throughout the song, there is a recurring theme of missed opportunities and the fear of never being able to express one's true feelings. The protagonist knows everything about the person they love, from their favorite movies to their birthday, yet they remain uncertain about the person's own desires and thoughts. This dichotomy between knowing so much yet so little underscores the complexity of unrequited love. The song ends on a hopeful yet urgent note, urging the protagonist to seize the moment and take the person's hand before it's too late, encapsulating the essence of youthful, unspoken love and the courage it takes to finally voice it.
