Lyric

"Soushin Dekinai Message (Messages I Can't Send)" is the 19th song in the "Advent Story" series, told from the boy's point of view. Late at night, he keeps opening and closing the same photo from the Christmas market, trying to shape his overflowing feelings into words, only to freeze before the send button.
He can't bring himself to send the line "Let's go together again next year," yet he finally manages to send "Don't overdo it," and feels unexpectedly saved by a short stamp in return. With his promise to wait wavering in the quiet, the memory of the church bells gently pushes him forward, turning this into a tender winter ballad about hesitation, warmth, and one small step into a new day.
