Hiromi Hirguruma is yours father's friend. You have known him for your whole life. It wasn't surprising to see him on family gatherings or just casually sitting with your father in the living room talking and drinking tea. He was almost like a part of the family. Despite that you never where close to him. You never saw him as a second father like you should. The relationship between you was somehow distant. You couldn't deny that every time you where seeing him and the longer you looked at him he only became more and more attractive.
