Song Meaning
The narrator finds her thoughts consumed by a specific person, a stark contrast to her previous preoccupations. She questions her own behavior, realizing that asking about someone's type isn't her usual style. This shift marks a significant change, as if a blank slate has suddenly been filled.
The core tension lies in the narrator's burgeoning romantic feelings and the possessiveness that accompanies them. Seeing the object of her affection interact with others triggers immediate jealousy, described as a 'moyamoya' and 'kirikiri' sensation, leading to a bad mood. Yet, this intense feeling is quickly diffused by a simple smile exchanged in passing, highlighting the volatile nature of her emotions.
The lyrics cleverly use the metaphor of a blank answer sheet, '三週間前までは白かった' (until three weeks ago, it was white). This 'white space' represented a state of emotional neutrality or perhaps an unwritten future, which has now been filled with a definitive answer: '君だけが好きだってMy music' (I only like you, my music). The music itself is described as a gentle harmony, like grass swaying in the breeze, something she desperately wants the other person to 'feel' with their own ears.
This internal conflict between wanting exclusivity and acknowledging the 'selfishness' of that desire, coupled with the rapid, almost uncontrollable growth of these feelings, makes the song resonate. The narrator's emotional landscape has been irrevocably altered, transforming from a blank canvas to a vibrant, albeit sometimes turbulent, composition, all centered around this one person and the 'lovely music' they inspire.
