Beautiful yet incredibly sad love story. The more he tries to make things right, the worse things get... but despite everything; Kyra still loves Donovan and keeps encouraging to try everything he can to save her somehow.
I can tell you all really put your HEARTS into it indeed. I imagine this took a few months to make and cleanup the animation, making sure everything flowed together perfectly with the music. Hopefully you all can work on more stuff together in the future. I think you all made a great team in putting this together.
Kind of curious what happened after the end, but I think this is one of those cases that it might be best to just leave it a bit open ended as to whether he manages to heal her or not. ;-;
