TATU - Gomen Nansai (Asian Anime Version)

TATU is a supposedly a teenage (well not anymore) lesbian act that has been sexy, controversial, and absolutely unique at the time (more likely, they're simply bi as most girls are - there have been tons of reports that Lena and Yulia like boys just as much, if not more than each other, and there have been well publicized spats that almost ended their duet career in leu of going at it alone. But, let them have their fantasy and let us enjoy it with them!)

Gomen Nansai means simply, I'm sorry. This is a pretty ballad imo - Enjoy

[This is the Anime-Asian video version. The song of course remains identical.]
