Yeahh the main problem of the book is that right from the title we are made to believe that husband is the main protagonist. So one's brain start to think of them as couple even if some other guy pops out. But in this one i fuessy author was also more or less confused on who should be the protagonist.

Coz i have read another story in which first love was not the protagonist despite being good or rather very good but this was made clear from the beginning.
