Caleb being so into time and then falling for the time guy™, yes, but also. Essek’s journey later on being all about changing, to be better, to grow a conscience, and alongside falling for the literal transmutation wizard, aka change guy (™)
It still hasn't sunk in that we beat both this game and this entire series... I'm gonna miss this weird-ass franchise, with all its faults and strokes of absolute narrative genius. Thanks for the wild ride, Danganronpa.
