This work is composed of three parts; the lower box, the top heart and the 3-leaf clover with three hearts. The lower part does not open freely and the top heart looks a bit lonely. In the middle, the 3-leaf clover composed of 3 hearts is the same as the heart on top. Maybe people who are quick to understand have already noticed the answer. But can you move the devices as you think? I hope your own “Chance Meeting” will come to you soon!
