Mid-Door Sniper

"When I was a child, the windows were all sliding and there was no anti-theft net, and the screen windows could not protect against mosquitoes. When I opened the window, I could see the blue sky and white clouds. Every time I sneaked up to the window sill, my parents would drag me back, for fear that I would accidentally fall downstairs. Such windows are not safe, soundproof, anti-theft, or even mosquito-proof, but they can pass things, pass notes, and make friends upstairs and downstairs." And this is a story about upstairs and downstairs. During the winter vacation of the first year of high school, because the Internet cable was unplugged and he was not allowed to play games and watch anime, and the door was locked and he couldn't get out and refused to do his homework, downstairs angrily found out the animation episode of piano playing at the first level of the tenth grade certificate to vent his anger. Upstairs, who was slightly socially terrified, couldn't stand the magical sound downstairs and didn't dare to go downstairs to confront people, so he had to open the piano he had practiced for many years and backhand angrily. From then on, the two started a daily routine of confronting each other. "Brother Yi, while you are not yet eighteen, are you considering falling in love early?"
