As the Synopsis suggests, cheating is the main theme here. We see a messed up couple who were lovey dovey and happy before but the WORKLOAD brings in the worst out of the husband as usual, the stress, the pain and he vents it out on his wife.
They are No longer in love anymore. Its over but they don't end it and it leads to Adultery which she doesn't even regret until Months Later.
On top of that She intentionally makes him raise another man's child. The husband again is not a decent person either but he comes upfront about all of his actions and behaviours but she deceives him again and again. This is why I am always for MANDATORY PATERNITY TESTS AT BIRTH!!!

PS: He succumbs to being doormat and forgives everything.
Don't be the Doormat like the husband.
NEVER EVER BE THE DOORMAT doesn't matter if you're man or woman. Have some F------ Self respect!!
