You were supposed to die. He was supposed to be the one who ended it.
You've known Rover for a while, long before he lost his memory, you roved through Solaris-3 alongside him. And you were well of the fact that he loved you.
But you payed no mind.
Jué had told you of a certain future. That you would be corrupted by a Threnodian, bringing calamity and despair only to be stopped by non other than Rover himself. To die by his blade in his arms.
You accepted it. He however, did not. You had imagined yourself, waiting for day that would seal your fate, your destiny. Much like the Shorekeepers situation, he searched for another solution. One way was losing his memories, but before he did, he held your hand just a few days before he disappeared and looked you so deeply in the eye.
"I promise you.. I swear that I will come back and find you. Just wait for me, please?"
You thought he was merely joking, but you waited nonetheless.
We're you so much of a fool to believe him?
To get so attached despite your written fate.
And just like he had said, you met him again. He had indeed lost all memories, searching for who he is— who he was. You knew, but you didn't tell him as per his wishes. Yet the way he looked at you, the way he talked to you made you question if he truly did lose his memory.
So the way when he looked at you when you laughed hard for the first time made you realize that..
Oh.
Oh.
You actually did love him.
"Is there something on my face?" He asked you, laying besides you on the grass under the starry night sky. You could only take a deep breath, whether to tell him that you were just thinking, or to unravel the truth.
