Do u think Miraxus will ever Happen?

Hello, I am new here
I know u might have heard this alot, but I really ship Mira and Laxus, and would really love it if they became true, I know FT isn't a romance manga and all, but we had some teasing about several romances, sometimes on Chapter covers, like issues 210, 213, 255, 239, 280,221,123 to name a few.
Also, do these covers actually mean anything special? of just teasers???
