It's all because of the rain

"Zenbu Ame no Sei" (It's All Because of the Rain) is a chill-pop track that calmly yet evocatively portrays the languor of a rainy day alongside lingering memories of "you."
The sound of rain-falling continuously from start to finish-envelops the entire song, seemingly bridging the past and the present. Amidst the ordinary scenery of a rainy day, memories of the time spent with "you" gradually come flooding back.
Layering a vocal style that leaves room for breath-a departure from Samezame's usual approach-over the sound of falling rain and an atmospheric, floating soundscape, the song captures the bittersweet, inexpressible ache of romantic memories resurfacing in a fleeting moment.
