最初からの「誰も一人にはさせないよ」めちゃ好き! I'm tired so I can't write properly in Japanese today, sorry. This song is so good!! I love the small details on the MV, the lyrics distributions are so well done thinking about their usual interactions, the lines fits the song and you can see each member's personalities so well on the song. It's probably my favorite original song from Piece Palette now. I hope this year's Christmas will be a memorable one for everyone.
