I want an anime which also has a romantic plot for adults like in blood+(david x julia) and gundam seed(i don't remember there names), eureka 7(forgot the names), blast of tempest(detective lady and the red haired guy) -Something like this, were there is romance between the adult characters as well -And it should be a happy ending for them as well. -It can be of any genre and not just only romance -Mention the couple also & they can be main or supporting characters either -No harem anime please.
