"Even if we're separated, again and again, I will find my way back to you. I promise, I will find you. Even if it would took thousands of years." Yuu and Ashera, two souls that was separated for ages. Their meeting on that day is part of their destiny, and by destiny too, they're separated. A promise was made under the sun, under the same blue sky as today, in the same world. How tragic that they reunited without remembering it all... This fanfic is inspired by chapter 69 of the manga and is my headcanon of what their relationship was like long ago, before they forgot about each other. CONTAINING SPOILER OF THE RECENT MANGA CHAPTERS! Main inspiration: https://goo.gl/N8x4CB
