You mean to tell me there is a story where people mess with time travel to change the past where nothing goes wrong at all, everything works out for the best at first try and everyone basically lives happily ever after???
Seriously, in 99.9% of all stories that do that, something ALWAYS goes horribly wrong. So it is kinda remarkable when it just...doesnt.
Hint 1: >!The guys who came up with the time travel idea are different from the person doing the time travelling who is ALSO different from the MC....who just got roped into this whole mess without being asked. Kinda.!<
Hint 2: >!A fairy regularly yells at you. No this is not a Zelda game.!<
Still no right answer it seems.
Hint 3: >!Time travel is not actually an active game mechanic but more like a story-telling element.!<
