Side Story 3
2. Reunion (2)
After entering the gap between dimensions, Jin-Woo developed a habit he never had before. And that would be jotting down things he saw and experienced on that day on a notebook.
He wasn't doing it with some lofty purpose of leaving behind the records of his bitter life-or-death struggle against the Sovereigns.
The gap between dimension was a perfectly 'empty' space, pretty similar to the land of eternal rest. Without battles against his enemies, this world of nothingness where only the eternal darkness existed would have been incredibly dreary and lonesome - he'd have difficult time trying to keep his sanity as a result.
However, his reason wasn't as simple as there being nothing to do in here.
Jin-Woo now possessed the experience of living the same timeline twice and because of that, realised something crucial – the perspective on an event would shift depending on when you were looking at it.
