Haru has given up on love and life. His past relationships had been nothing but failures, and his friends and family had abandoned him, leaving him to live a life that feels empty and meaningless. He saw no point in life anymore. Why bother looking good when everything around him was already falling apart?

If someone did manage to break through his shell, they would become his world, his everything. They would be the only reason for his living. He would do anything to keep them in his life.
