| [00:11.14] | 華やぎうつろえど 変わらぬもの |
| [00:21.57] | 一途に香り立つ 想いは胸に |
| [00:32.71] | もどかしいほど愛しさは |
| [00:43.02] | 綺麗な花をつけるでしょう |
| [00:52.84] | 心を染める紅 凛として |
| [01:03.29] | 寒空にも映える 寒椿 |
| [01:14.48] | |
| [01:34.63] | うらはらに言葉は 宙を滑り |
| [01:45.08] | それでも伝えたい いついつの日か |
| [01:56.11] | ひたむきな歩みに水を |
| [02:06.58] | あなたの傍でこれからも |
| [02:16.41] | 心を染める紅 凛として |
| [02:26.82] | 強く優しくなる 力となる |
| [02:37.23] | 心に燃える紅 花をつけて |
| [02:47.02] | もっと紅く、紅く |
