May be they have named their main characters with the qualities they do not possess!!! Ichcha- sacrifices her desires for others. Veer- has no 'veertha'. Tapasya- total opposite of the meanings given by arunimaji. Vansh- his Khandaan feels ashamed of his drug habits and locks him up!!! So the story may move in such a way that Ichcha gets her desire (or happiness), Veer acts with courage, Tapasya really repents(?) and does some tapas (which is very unlikely!!) and Vansh upholding the family name by behaving nobly. Let us atleast hope for the best!!!
Why Taps CVs should look at it how they have killed the meaning of that name
