Soyboy Clock Link on RRL has multiple main characters, both males and females. It's my favorite RRL story and doesn't really have much romance, it's a mystery action story.
I suppose I can also be shameless and suggest my own story: God Vessel Online. Also doesn't really have much in the way of romance, the focus is more on the MC being a closest gamer and getting an opportunity to play a VRMMO. A casual slice-of-lifey story.
