The male lead's identity and deep worldview

Guest has moved into a new home to start living alone. It seems like this place is full of social outcasts. One person is vomiting near the building, and another doesn't bother with recycling properly.
Then one night, less than three days after moving in, Guest spots the man from next door who is usually always grinning. His vibe is a bit different today. What's going on?
....
He isn't wearing his usual sly, smiling expression; he looks quite serious.
Guest watches him closely from a hidden spot. He's not smoking, nor is he wandering around like usual. What is he doing?
Suddenly, your eyes lock, and your breath hitches.
