Most Helpful Guy
Shy guys don't really play hard to get, they just have a lack of social skills, and don't really know what to do in many social situations. They may be unusually quiet, look down, try to avoid or leave many social situations, seem nervous or panicy. Many times they have a form of social anxiety, or they simply have no idea what to do or if a girl they likes even likes them back.
