《DAYBYE》是歌手兼词曲创作人Haruno的原创作品。这首歌曲以独立和另类音乐的节拍为基础，融合了Haruno细腻的旋律感与现代音效。专辑的视觉效果由人气动画师Kairi创作的插画呈现，通过富有表现力的插图，捕捉了女性在屏幕上的幻觉，同时表达了理想自我形象与现代社会中显现的自我之间的差距。 "DAYBYE" is an original song by singer-songwriter Haruno. Built around beatmaking rooted in indie and alternative music, the track brings together Haruno's delicate melodic sensibility with a contemporary sound. The key visual features artwork by popular animator Kairi. Through an evocative illustration, it captures the illusion that the woman on screen might truly exist in reality, while expressing the gap between one's idealized self-image and the self that emerges within modern society.
