Kokoro Connect is a great series. It allows the audience to seriously feel the fear of their inner being laid bare for others to see. In each of 4 arcs, a mysterious being FuusenKazura triggers some kind of phenomenon to occur to the 5 characters that allows, and forces them to see parts of each other private lives which they would normally keep concealed. For instance in the first arc, FuusenKazura causes the 5 to switch bodies with each other. Thus these five who have never shared the naked fact of their family lives, or lives outside school generally, now experience each other live first-hand. The series lets you to realize ho little you might know those people that are closes to you, and it forces you to be honest about how little you let others to know about yourself deeply.
