Anup has come to know that shiv is his son after 25 years.He's going through a lot of emotions right now.He's acting in a matured and sensible manner but somewhere in his heart he wants to show his love to shiv and he can't do that openly.Giving that medal and tie to Shiv was only an expression of love from Anup's part.
Anup is not sure how to express his love to Shiv and hence he's doing these sweet gestures...just what I felt 😃
