KS is a typical honest, emotionally strong but sensitive male and has typical characteristics of such persons:
1. Honest but the honesty is too much for anyone and most of the persons around get hurt.2. Don't care attitude - for others but to loved ones - they're always sensitive but most of the time hidden.3. Loving but not ready to accept / confess in person4. Sensitive to others but cruel to self in terms of emotional matters. In the last episode he didn't hesitate a bit in telling the truth to Ananya. It was painful to Ananya but KS is feeling more pain and hurt.5. Believe in only giving and never ready for accepting anything.6. Whenever such persons have to make a choice to hurt other or self they will hurt self. This may be typical of the caring and loving persons also but the tendency of sacrifice is of a higher degree in persons like KS.The whole show is KS based - on his honesty and his character. He is incomplete without Ananya who is a normal bubbly girl and loves her life - the journey of their love is going to be painful (unless the characters are changed by CVs twists)IMO he will never confess his love for Ananya but will always suffer and be in pain because of her. Its the destiny of such honest and sensitive persons who do not want to accept that they are emotional and just put a veil around them.
