their space factor and flow for passages is js not it,, if you look at their kitchen, their dining table is kind of blocking their way to the workspace and other spaces, which is generally not a good idea, even if the place is for one person only. the passage to the laundry room is also too narrow. for a person to squeeze in, basing on the sketch of the characters, they will have to walk sideways ? not ideal. and their toilet's door is facing the main door which is also not ideal... if you put it in a scenario where someone just went out from that bathroom and coincidentally, someone also went inside the room, wouldn't that be awkward? especially if it is a guest. I am also assuming that their toilet have a sliding door. and the toilet and the sink should swap places... over all the spaces are too narrow for a person, let alone to people..

I am so bothered by their floor plan in ch1 im so sorry
