Yeah i know. I just recently finished Carl's & Leo's route like an hour ago, and my heart dropped at those lines.
I just can't help it to get attached to them. I mean, how can you just not love William and Nickolai (and Cyntia)? They're like... rare pokémons that needs to be treasured lol
The creators of the Echo series doesn't seem to have "good ending" in their vocabulary. I mean I guess they do, but their type of good ending leaves you questionably happy yet depressing. Its like The Conjuring but with romance and the credit song is WAP but sanged by Celine Dion lol
