He is a doctor who is familiar with people's hearts. He is an autistic young man who was hurt in his childhood.
When he met him, he already had a partner with whom he had been in love for many years; when he came for treatment, he had only taken care of his neighbor for more than 20 years in his life.
He yearns for the beauty of family, he doesn't know what family is.
He is just an ordinary man who wants a mutually supportive love; his beauty makes people commit crimes, and in the midst of hurt he only wants a warm person.
This is love at first sight, which can also be regarded as an empathy reaction in psychology.
When the right person appears at the wrong time, how do you choose?
