Aliasing mates → romantic_couple
Link to alias
Reason:
Same usage.
They're not all particularly romantic, but neither are many posts that get tagged as romantic_couple. Because that was just a generic 'couple' tag before the rename, and posts involving couples don't always have romantic connotations.
(Something like 'loving_couple' would've probably been a more accurate name.)
EDIT: The tag alias mates -> romantic_couple (forum #212666) has been approved by @Rainbow_Dash.
