The little mushroom goes to that office to get a new job, things get messy and he ends up on a train to the inner city, the ML is on the same train. The part of the city they're at now, is being destroyed and the old man and Poet die.
After that they get closer, new characters appear, he finds his spore and it's revealed that he's a mushroom. The mushroom wants to go back home, ML is supposed to "hunt" him, but can't and many other things happen after that as well, plus another couple get's back together
