It is just my opinion… not to hurt feelings of any one or against anyone.
Each individual has its own personality.
Indira has a personality of her own. Serious about life and responsibilities rather than personal comforts and personal preferences. She lived inside a shell and make a fence around her. Shell is her family and the fence is her responsibilities…. that is the simple life of Indira for many years. It reflects that she is very committed to her responsibilities and separated from the rest of world. Preferred more privacy.I guess.
She took time to express her love and was only when she felt that she needs a support of a person who understands her. It reflects that she is not too much romantic to express openly. Her love is more attached to the heart and emotional.
Gradually she started liking the personality of Rishi, when all the misunderstandings are over. Sincere to her love and gave preference to the love. It reflects that she is committed to her love and liked Rishi as her partner.
When she got separated from Rishi, she worried about him but not cried and not expressed her love or feelings in the form of huge tears. Rather she suppressed her feelings and searched for the cause who did it?( Kidnap). It reflects that she gives importance to the things what next to do rather than thinking of useless things or rewinding the memories. She concentrates more on how to solve or come out of that problem.I guess.
From her personality it is clear that she takes hasty decisions in anger and relies more on other person or his ideas in sorrow .I guess.
