LOL, of course the place you should ask for it is at the Nacchi thread
I don't know where to ask but... does anyone have the instrumental of Koi no Hana? Is there an Instrumental of it?
Anyway, here's the instrumental for the song
If you like this song, you MUST see the PV. It's one of my favorite Nacchi PV everrr
Just try youtube. You won't have problem finding it there
