Okaii let me clarify my response because your post come of as Taani should be held thankfull to Sharon and Swayam and they are her guardian angels.
Because lest face it Swayam is her brother and if one thing both should have for each other is uncondiitional love for each other whether it is love or if their fighting.Both should get over it because they are siblings and anyway its not suppose to be a give and take relationship like others.Swayam is her older brother so his concern for her is not him being or doing a favour on her .She is his sister and when you get tagged as a brother you expect these things.Second Taani and Sharon before Sharon sue to do things for Taani or whatever because of Swayama nd that she is his sister not because they share any personal equation with each other.
As you said Tani expect from Swayam. Kyun? They way she is behaving with HIM too, does she deserve to expect his brother to come and wipe her tears even if she is insulting him and even doing batameezi to him.
And about Sharon. She CARED and even LOVED a bit ab woh Swayam ki wajah se ho ya kisi aur ki. But the fact is she did and then Tani can't say now that Sharon was always bad to her.
