Anna is now a stoic queen. She reflects on the past, how the royal sisters' taboo relationship was disastrously exposed. Elsa, knowing that the public would target her with the lion's share of blame, devised a plan to preserve Arendelle's royal line. Though Anna desperately resisted, she ultimately agreed to support the ruse that Elsa had magically seduced her. Elsa fled to the wild, reviled as a witch, while Anna retained public support as queen. But still she looks to the mountains...
Edit: I kind of messed up as i wrote this sleep deprived. Sorry its not from Anna's point of view as requested.

They would have never been caught if it wasn’t for the intensely dry hot summer. Through the windows Anna’s bed room lit up as lightning flashed through the sky. With out knowing it, Anna and Elsa continued to make love as that very bolt struck a tree, setting all of Arendelle on fire.
A servant burst into Elsa’s bed chambers with the urgent news to find their queen absent. Rumors had already started about the sister’s involvement and so the next stop was Anna’s room.
It was a horrifying memory, but it was all Elsa could ever think about as she stared out over the frozen landscape from her ice palace. She couldn’t believe how fast guards and staff members had flooded in to Anna’s room pulling the queen away from her sister with no regard to their state of undress, already deciding that neither no longer were worthy of modesty.
Elsa was quick to shout out that she had put Anna under a spell. She had it all planned out, her story. She couldn’t not be prepared for the worst. Not when Anna’s life depended on it. Now, nearly a year later she was glad she had, despite Anna’s protest to the plan, or for even having one at that.
The towns folk had accepted the story and with pleading from Anna they simply banished the ice queen. Elsa had kept an eye on Arendelle through various means and was glad to find they had accepted Anna as their queen and no harm had be fallen her.
She had even heard of Kristoff and Anna’s wedding just days ago. “That should be me,” Elsa said bitterly. Her hands tightening in to fists.
"You are right. It should be."
Elsa spun around in shock at Anna’s voice. Her sister was standing before her in the door way.
"I am really sorry it took so long! Who knew finding someone that looked exactly like me would be so hard?" Anna said tucking a strand of hair behind her ear nervously.
With out saying anything, the princess had devised her own plan after she failed to talk Elsa out of taking the fall. She figured they would let her rule, but without Elsa there was no way she would stay in Arendelle. So her and Kristoff spent a lot of time working out the details. They spent a lot of time looking for not only a young woman that looked like Anna but one who could rule beside Kristoff in her place. Sending word to Elsa of their plan, they decided, would be too risky.
"Anna what are you doing? Do you want to be killed? Why are you here!? You need to leave now!" the ice queen found herself angry. What a foolish girl!
"The answer to all those questions is; No, I am here to marry you. I know there wont be any witnesses or a party really but… I don’t care! All I want to do is be with you." The red head took a step towards the ice queen but Elsa huffed and turned on her heals.
Elsa was livid. She had sacrificed everything for her happily. Gave her an entire kingdom! This is how she repaid her by…. by loving her. Suddenly her anger drained from her. It was then replaced by dread. She could easily live in isolation knowing Anna was happily married and safe, but now?
She felt a hand on her shoulder.
"Elsa, you know I can’t truly be happy unless I am with you right? Down there, I was just as lonely as you are up here."
Elsa felt tears trail down her cheeks as she pulled Anna into an embrace. Whatever happened they would go through it together. It was Anna’s plan and right now all the ice queen could do was trust in her like her sister had trusted her before.
