Why is Sooraj jealous of Kesar?

In the 6th December 2023 episode of Kyunki.. Saas Maa Bahu Beti Hoti Hai, Kesar announces her decision to get married to Sooraj.

Ambika announces Kesar's decision to the entire family who celebrate the occasion with Ambika and Kabir's dhol music.

Ansh calls Aarti to inform her that his marriage has been fixed by making her listen to the Dhol music.

Aarti feels afraid as Ansh is getting married to someone else. However, Ansh calms her by saying that he is only making fun of the situation as it is Kesar and Sooraj's pre-marriage celebratory music.

Ansh convinces Aarti that he knows both of them love each other and he would like to take the relationship ahead.

Hearing Aarti and Ansh's conversation, Shakuntala thinks that he will ensure that Sooraj and Kesar's marriage never happens as she wants Kesar to get married to Kabir. 

Also, she becomes happy that Aarti and Ansh are dating each other as this will help her settle both her son and daughter in Rajgaur's house.

Sooraj while listening to Ambika and Kesar's mother-daughter conversations feels jealous of their bond.

Sooraj says to himself that he has always been kept away from his home only because of Kesar.

Sooraj also feels angry over Ambika as she is always concerned about Kesar and never treats her own son as his child.

Sooraj says that he will set an example of how a daughter-in-law and wife should be treated after he gets married to Kesar.

Kabir is in a dilemma as Kesar is getting married to the wrong person like Sooraj.
