Give Me a Kiss to Build a Dream On!
Make that two!
Despite what has already occurred in the manga, anime and movies I would very dearly love to see a real proper passionate kiss shared equally between the two main couples - namely Inuyasha and Kagome, Miroku and Sango - before the anime series ends.
And, yes, I know Kagome kissed demon Inuyasha in the Castle Beyond the Looking Glass and Sango planted one on the unconscious Miroku before leaving to fight Naraku. Those don't count, I want both people to be fully aware active participants.
