back number - Even if I someday forget

A breakup song by back number that has captivated many with their love songs.

It’s a track included on their first album, “Ato no Matsuri.” I want to become someone who, even just once, would make the person I broke up with think, “I don’t want to forget you.” We may part ways now because we’ve grown distant or started to dislike each other, but being someone that the other person doesn’t want to forget—a presence they want to keep in their life—there’s a kind of pride in that, isn’t there? Whether I can become that kind of person, I want to be… back number has a way of singing those faint, earnest feelings in a completely straightforward way.
