(although judging from the look of actual screenshots of said show, it was probably a Japanese sitcom rather than a drama a la Law & Order xD

pretty sure it was never used as a love hina theme... or any anime OP for that matter.
in fact, nothing by that artist has EVER been used in an anime.
no, apparently it was made as the theme song to a live-action drama about a third-rate (((LAWYER)))

just an error that happened when animating it in photoshoop that i didn't catch until after i posted it :P
i just uploaded a fixed version
