When Ajay discovers that his wife is having an affair with his friend, he receives advice from a stranger who has a mathematical theory of romantic success.
The mathematician character, whose name is Ram like the author's, spends a few pages talking about the power and importance of mathematics and the mathematical theory of relationships  in which two numbers are assigned to each person and the ideal pairing is identified as a Nash equilibrium  is explained in some detail.
And the existence of this theory affects the course of the novel as Ajay follows Ram's advice.
If the mathematics was removed, there would not be much to this story. A husband discovers his wife's affair and he learns to deal with it. Perhaps that is an unusual plotline in Tamil; maybe addressing questions of love and compatibility is itself unusual and would make this an interesting read to someone in India. But, in English literature, this is all "old hat".
So, presumably any interest in this books would lie in the mathematical theory of love that it proposes. Loosely put, the theory attaches a pair of numbers to each individual by identifying the number of needs that they have and the number that their current partner fills. It is claimed that a stable relationship is one in which the partner has the same values in reverse order. Justification for this theory is based in part on a stated belief that there is a divinely selected perfect mate for each individual and by reference to game theory. However, in the English translation I read (provided by the author) I'm afraid I did not find the mathematical theory of romance that this book promotes to be sufficiently interesting or believable.
I thank the author for bringing this work to my attention. This novel was published in India by Kavya in 2017. At one point the author notified me that an English language version was to be released in India by Emerald Publishers under the title "Those Faulty Journeys".

I recently came across this list while I was searching for reviews for this book. Honestly, this is an awesome collection of math fictions. Kudos Alex. But your review makes me to think, you have not understood some portions of the book. But, I also think it should most probably be the 'unconscious bias' when a Asian author tries to put forth his ideas in a language not native to him. Very unfortunate.
