DerekHandley suggested Groot and Poison Ivy.
I had tackled the same subject the previous year in a more cartoon-y style which I really didn't like (it's on here somewhere) so I really wanted to do a version I was happy with.
I'm happier with this.
I suspect most people will assume that Groot is under Poison Ivy's chemically induced spell, but no - they are just really pleased they found each other. Hey, it's Valentine's Day!
