ADN-444 Secretly love the neighbor who is married.

A difficult-to-approach neighbor doesn't greet you when you pass by each other. She seems to have a boyfriend, and at night, she always hears heavy breathing. She is beautiful and has good style, but for some reason, she always appears to lack confidence. Why...? As I was thinking about this, I heard an angry voice from the next house. When I went outside, I saw my neighbor sitting on the ground.
