Sheep, sheep, so many sheep, it turned out that wheat sang. This song is included in Mai's album Tears of Gratitude, written and sung by Mai himself.
From "sheep, sheep, so many sheep" lyrics: sheep, sheep! There are so many sheep, who can hold them in his arms and care about them? Sheep, sheep! There are many sheep here, and they are always put on the green grass and beside the stream. I don't want to hear that the shepherd is sinking into the sea, and I don't want to see that the shepherd has an employee's heart.
