This is the English subtitled version of:
Song#28: 愛言葉 (Love words) from Hatsune Miku 39's Giving Day Concert.
Trivia: The concert was held on the 9th of March (3/9) because 3 and 9 can be pronounced "sankyuu" in Japanese, which is the japanised version of "thank you". There are also a total of 39 songs in the concert! Very nice planning by Project Diva and SEGA (and whoever else is responsible for this event!)
3 and 9 can be also pronounced "mi ku", which of course is Miku!
Hope you enjoy this song, and BUY IT (the blue ray of the concert if you like it!)
"Love is 10 = thank you" in Japanese, "ai ga tou = arigatou." They basically just sound similar. Numbers are used as shorthand sometimes.
