until my heart catches up

"Kokoro ga Oitsuku Made (Until My Heart Catches Up)" is the second song in the "Advent Story" series, telling the girl's side of the promise made on Christmas Eve.
When her childhood friend honestly says he will wait for her at the church, her heart is caught between happiness and fear. This gentle winter love ballad follows her as she asks him to "wait just a little longer," wishing not to lose the precious bond they share until she can truly let her feelings catch up.
