ADN-444 Secretly in love with my married neighbor

An unapproachable neighbor doesn't greet you when you pass each other. She seems to have a boyfriend, and at night, she is always heard panting. She's beautiful and has good style, but for some reason she always seems lacking in confidence. Why…? As I was thinking about that, I heard an angry voice from next door. When I went out, I saw my neighbor sitting on the ground.
