ACCEPTING 'US'

It is a story set up in 1990's...
Sudha is a very beautiful, kind and honest girl. she has all the qualities a girl should have to get married. but sadly her marriage is not getting fixed. all the suitors come, see and then reject her.
Why? what is the reason for the rejection when she is perfect?

" I guess you know what this means? " he asked slowly coming near her. she nodded her head but she didn't know what awaited her later. she was now trapped by the wall behind.
" tell me what you know about husband and wife? " he asked placing his hands on the sides of her face. she looked here and there not knowing what to answer.
" look at me sudha " he said in a pleading tone which made her stomach twist in an unusual way.
" I.. I ... " she stammered not knowing how to answer his question.
" I am hearing sudha. tell me what you know? " he asked again making her uncomfortable by moving close to her.
" I.. I do not...kn..know. that my friend was saying that husband and wife will have a different relationship than any others. I promise I really don't know what it means " she said while placing her thumb and index finger on her throat while he burst out loudly. she stood there confused until he calmed down.

Sudha got married to Shyam after many rejections. but due to her probelm she always faces backlash.
she is handicapped. yes she is born like that and she is often a laughing stock in front of people.
Let's see how sudha will face this humiliation after marriage as before marriage she has been a part of disrespect and humiliation all the time.
how is shyam going to help her? or will he really help her?
