I cried so much... I remember playing this when it was first in beta as "Dragon Dating sim" and you could help support the game. I never realized how much it changed...
The characters feel realistic and all have very touching backstories. Get to learn all them and learn what makes them tick was extremely moving.

As I can not explain the game without giving spoilers, I completely reccomend this. Just make sure you have a comfy chair and time, as you will be taken on an extreme emotional rollercoaster.
