Translation: Happiness goes to Hell.
Suddenly, you experiences abnormalities in all five senses except taste and touch.
Even at a convenience store, what used to sound like "Would you like a bag?" now sounds like garbled nonsense, and a perfume that once smelled pleasant now feels like a toxic stench eroding you. you grows terrified of the sensation of dissociating from society.
"Can I come in?"
One day, the intercom rings, and when you steps out to the entrance, a small child is looking up and saying that.
Overjoyed at finally being able to have a proper conversation for the first time in a while, you lacks any sense of danger and casually lets the child inside.
From that point on, a surreal daily life with Rashika begins.
Note: In terms of holding on to the human society that is gradually isolating you, and returning to normal human society by leaving Rashika, the difficulty is extreme.
