Request Looking for a song

It was a love song about a girl watching over this guy as they grew up. One of the lyrics went something like: four, five, six, even as you fall down. seven, eight, nine, I'll still be by your side. That was the only lyric that I kinda remember. Likely a Vocaloid song, maybe by Honeyworks? If you guys could help me find this song, I'll greatly appreciate it.

 

but maybe you're looking for Judy's ver? the lyric is a bit different.

 

i feel like i kno it.

 

I am not exactly a fan of vocaloid but what you described does sound like a vocaloid song to me and a one starring Hatsume Miku at that
