This book is not intended to encourage men to toy with love, but to help them understand its nature and find a life partner who shares their ideals. Let me make this clear from the outset: love is sacred, but it cannot be denied that love is not as bewilderingly mysterious as people think. Love has fundamental patterns, and it is grounded in reality. Of course, knowledge is endless, and no one can master it all. Some things said here may not be entirely accurate, so readers should consider them critically and from different perspectives. Lastly, I want to state that I respect women and have no intention of discriminating against them.
