Mizushima is an aspiring picture book writer. He suffers from obsessive-compulsive disorder and has an overwhelming fear of germs as well. This makes it impossible for him to touch anything and anyone directly, even his girlfriend Kirimoto. They have been in a romantic relationship for a long time, and they care deeply about each other, but Mizushima is unable to touch Kirimoto or hold her hand.
Finally, Mizushima decides to seek treatment for his disorder. At the hospital, he meets a woman named Chiharu, who suffers from the same disease as him. Meanwhile, Kirimoto works at a bookstore as a clerk. She understands her boyfriend's disease, but she still agonizes over her relationship with him. She then meets a man named Lee.
