In the years of my reckless youth as a student in Novosibirsk Akademgorodok I began to think about the nature of love, then my interest in the thrill of the soul became stable – I began to write something down, to note the nuances of my own and observed love stories. Studying psychology at Moscow State University gave a new impetus to thinking about love. Somehow the idea came to systematize and to share my, hopefully, unhackneyed thoughts, but it took 25 years before this was put into a book.
