Need Help Finding an Old Vocaloid Song!

[Lavender]

I've never done this before but I'm helping a friend look for an old song!
I'm not sure if this is the right place but we'd love some help!

She's unsure if the original song was Vocaloid or if it was a cover, but she remembers the cover art with miku, ren, Lin, luka, kaito, yuki, and kiyoteru standing together.

She also remembers sakura trees on either side and the song should be about 10 years old. All she can remember about the lyrics is that there was a line that goes.
" honto wa kizuiteru"

We'd be super grateful if anyone can figure this out for us!!

If you add Miki and Gakupo, it sounds kind of like this 2010 vid... but it's 15 minutes which I feel like may have been mentioned if this was it?

Currently nico is down, but heres a thumbnail:
