1 applying a reverse psychology by taunting her as shez jst being aaya of adi n ruhi she nvr became raman's wife shez behenji types blah blah just to make her move a step ahead in their relation..
2. rescuing her from Ashok's evil motive
3 praying n requesting n pleading n convincing Anda chor Manoj to DO THE BEST to treat ishita with her infertility
4.she became soo careful for behaved soo cautious during their surrogacy process with lakshmi...n thereby aftr knowing abt lakshmi's fraud she told to manoj
5. she became surrogate mother for ishra's baby...or shud i say moreover for ishita's happiness...she wanted to do this for ishita..as she was in love with ishita...
7. And Lastly...like sumone u trust soo much love sooo much..u do sooo much for a person...and in return if he/she cheats u or hurts u...u just become sooo voilent..
IF u REMEMBER WHEN RAMAN TOOK SHAGUN TO BHALLA HOUSE N TOLD THE TRUTH...AFTR THAT EVRY SINGLE PERSON IN BHALLA FAMILY TAUNTED HER SHOUTED HER ABSUSED HER TO UNLIMITEDLY..but shagun didnt loose her paitience as she knew she loves ishita n all this she did for her and whatever anybody says ishita will understand her...she wont taunt her... and will make everybody understand too..
BUT WHEN THE ONE HARSH LINE..from Ishita " ye bachha toh humara h par Kaash Ye KOHK TUMHARI NAA HOTI"
had brushed off her all good doings soo far ...THIS line from Ishita made her to get back to her earlier self..she understood no matter what you do for the one who has done sooo much for u...is all a waste..
CONCLUSION: THIS IS THE REASON SHAGUN HAD POSSESSED ISHITA ONLY...NOT EVEN RAMAN
SHE WANTED TO LET HER KNOW HOW DOES IT FEELS WHEN PPL TAUNTS U FOR WHAT WRONG U DO...N FORGET WHAT GOOD THINGS U DID FOR THEM
