I didn't expect so much to happen in a single day (or inside a room). Honestly, I was interested in the artstyle, but now I'm obsessed with the writing.
I couldn't help it but adore Demyan, not really him, but how he feels. I really like his way of indirectly communicating how he feels. Him liking elk's because they can shed their antlers says a lot. He's really self aware of him not being mentally well, his description makes it sound as if he wants to be like the elks and to be able to fully get over his issues. I do find it kinda sad that he's not able to give himself a space to "feel" (I say this since he claims he's too old as to act like a kid).
Edit because I forgot something. I'm not sure if this is a glitch, but if you eat and decide not to read, you're able to ask to eat before sleeping. I'm not sure if this is only supposed to happen when you make him mad by trying to break the window.
