Cliffhanger aside, when being visited by Truck-kun, between time travelling to when I was a baby and being isekai'd with no guaranteed cheats or world specification, I'd be crazy to not say time travel. There are a lot of mistakes I've made over the years that I can't let go of. Even if I got the chance to redo them or whitewash them with no one the wiser, they would still haunt me, but for the people I've wronged, or just not been there for, it'd be nice to fix them. And I'd be a genius baby, there's that, too.
