Na, I liked the premise more if this was 1 MC traveling to the past. Making it happen to two people, its completely unsatisfying for things like revenge or for future gains.
Ignore all that!
@Ghajik Ah, I forgot I posted this... Indeed, I did. Well, pretty much ignore everything I wrote above this. xD It's actually way better than I thought
This comic has a really, really bad start, but it gets back to its tracks real quick (within 5 chapters or so) and by the chapter 10 the story is just gold. 100% recommended.
