Yeah this season anupre love is far more deeper. Despite so many humiliations and repeated insults by anurag and even after being called a goldigger she returned to basu badi claming her rights and fulfilled her duties as a wife. She even told komolika "Humne komolika naam ke toofan ko hara diya hai aur aage aa rahe hai sab toofan ka ek saath saamna karenge ".Even anurag could have moved on with komolika unaware of her evil intentions but he didn't once pre decided to fight back. And jitna durga maa has given them signs of being together in this season utna toh season 1 ke anupre ko bhi nahi diya tha. They both easily moved on their lives after their first separation,anurag got intimate and started loving komolika while prerna became an independent businesswoman.
But Komo 1 was not a killer so they cud show them as wife husband.
