Seeing this as an alternative path to the original end, it's definitely a "good ending" but not the "best" and "true" end. Dere Kirino is definitely weird but HNNG-inducing. I'm actually amazed how this series has become a visual novel kind of adaptation where there are alternative paths to choose from.
Notable things:
I enjoyed it, this can be a good alternative if the original goes to a bad end.
