Renai Kanjouron

Even if I can see your heart, it's hard to fall in love with you. Ryoma, who has a special constitution, is able to see other people's emotions as symbols. One day, he meets Aoyama, a university student who has a "black blur" of emotions that he has never seen before, and asks him to use it as material for a psychology experiment. Ryoma agrees to be a part of the experiment for a limited time in order to find out what the black blur is, but... what exactly is the black blur? Will it turn into love someday?
