Normally I only comment AFTER finishing everything the build I played has to offer... but damn, this is very well-written and pulls at the heartstrings JUST RIGHT.
I only played what's currently available in Mikko's route, and I loved all the deep lines and metaphors (and the protagonist just makes me feel like they're suffering from depression), and I don't think I've seen romance novels (visual or not) go in the direction of the protagonist still not being sure of their feelings when the love interest confesses...
I'm looking forward to playing the other routes, but I need to take a break because that route broke me (in a good way).
