KBTV-031 Is a woman who looks sober and has a mature personality but can talk firmly with her eyes actually accustomed to a man and easily get rid of it? Theory

At first glance, she is sober and has a mature personality. It seems that he dares to avoid a man from clothes that can not be said to be cute even if he does not wear contacts. Normally, such a sober child who is not accustomed to men will not be able to take the next step even if there is an invitation from a man. However, I got a rumor that only a child who looks sober and can talk firmly without turning his eyes is actually accustomed to a man and can be easily dropped. This time, I have actually put my body to verify this rumor!
