It's a distance-sensing device expressing lovers’ intimacy. In modern society, marriage has always been a matter of concern for people, because everyone wants to be happy and desires intimacy. But at the same time, there is such a group of people. They're usually no different from normal people, but they have a hard time getting into intimate relationships. They behave differently in intimate relationships and are even called "scum" and "scummy" at times. These are the people with avoidant attachment. Through this interactive video installation project, I am making people aware of their existence and learning more about them. I also show the difference between the two modes of avoidant attachment in a normal and intimate relationship.
