Rumbling Hearts (2003-2004)

There are some non-graphic sex and nudity in the anime.

A female and a male character are seen in bed, hugging and bonding, after making love.

Another female character and a male character are seen having sex a couple of times in the show. Nothing graphic.

Woman's breasts are seen briefly.

A woman confesses her love to a man saying that she has loved him for so long but suppressed them because she didn't want to betray her best friend. She then strips in front of the male character. She is seen covering her breasts and the male character's head is blocking the rest of the female's nudity.
