The world is big and colorful Chocolate is delicious, but gummies are also delicious. I also want kindness like marshmallows [3節] まいにちがノルマになってしまった きみとのじかん、くるしくなって すきなのはかわらないけど ほどほどがいい、そう思ったんだ [コーラス2] Why is there only one? The world is big and colorful Chocolate is delicious, but gummies are also delicious. I also want kindness like marshmallows [間奏曲] why everyone Will you choose one? as if that's all there is to it There are actually many Even though I know [間奏曲] why everyone Will you choose one? as if that's all there is to it There are actually many Even though I know [間奏曲] [ブリッジ] どうしてみんな ひとつにしてしまうのだろう それしかないかのように ほんとうはたくさんあることを しっているのに [エンディング] Is it good to decide on one thing? Is it noble to choose one person?
