My Dear Marie. Good damn comedy about a science geek that makes an android that resembles an associate of his that he likes(except 'up top') and how she integrates into his life. 3 ep ova series.
I know you don't want an action series, but
Casshern was pretty good(the 4 ep 1993 OVA, not the 1970 TV series), probably known a bit more since Casshern SINS was made, but still a solid action series with a hint of romance.
Escaflowne's not on that list!? Good gosh man(or woman(>.>)) you need
edit: Escaflowne is popular. Nevermind =0p.
