I unexpectedly shared the sense of rainy weather with my neighbor downstairs. Whenever a heavy rain came, his heartbeat and hot breath would penetrate every inch of my nerves through the sound of rain. And a cold-looking fitness instructor moved downstairs, and he didn't even say hello when we met him on a sunny day. But whenever it rains, we are like a short-circuit, and our senses are all connected - he gets cold in the rain, and my heart trembles; he gets tired from working overtime, and my eyelids fight. The most terrible thing is that one night during a thunderstorm, I heard the beating of my heart mixed with his low breathing while calling my name from upstairs.
