Kristoff of course. Her love for him was real!
Hans would've been a better choice or Anna!
Hans is a power hungry jerk. I love Anna and Kristoff. Long live Anna and Kristoff!
Hans was power hungry and would have likely killed Anna sooner or later.
Having Hans be evil was a mind-blowing plot twist. Well done, Disney.
If Hans married Anna, they would have been happier, since Kristoff is poor and if Anna went with Kirstoff, she would regret. But Hans is rich, and he is loyal too, just like Rose and Jack in TITANIC, is Jack didn't die, then Rose would regret the rest of her life.
