Fruits Basket - I Will Believe This is a reflection of Kyo and Tohru's time together through out the anime. It's not Tohru's perspective nor is it Kyo's perspective. This video combines both individual and unique perspectives.
Note: Sometimes, the subtitles do apply to the song, so please try your best to read them. If there are random ones, well, that's how the video clips I uploaded are. =P Enjoy!
