Late at night, a girl who has just returned home from work answers a call from her best friend, who is complaining about what happened to her during the day. The girl doesn't take her best friend's concerns seriously. However, when the same thing happens to herself, she realizes the seriousness of the problem. There is a barrier between people's hearts, and stereotypes are one of the reasons for creating this barrier. But the real danger often comes when one relaxes their guard.
