Back to the FD PV+song, that song brought me so very close to tears, especially because of the fact that it was aimed towards a true Hikki fan.

It's such a beautiful song and Kiriya did a wonderful job with the PV, he really brought out the emotion. Deep River was also a very sad song, which brought me close to tears as well.
EDIT:
Because of all this talk I really want to place Passion and FD in my MP3 player again
