He is indeed jealous of krishna, krishna married the girl he wants and love, while Shakti, married someone that he didn't love or wanted to in the first place. Shakti, did make a fuse over krishna honeymoon, he told his father he wanted a holiday without kesar.I think it's an entirely different reason. According to me, Shakti wasn't happy with the news coz he thinks that everyone in life is happy and content except him. 😲
I think Shakti has always felt dejected that both his brother and sister got the better of everything. They got good looking spouses while he got stuck with Kesar, they have happy married lives while he obviously doesn't. Krishna is obviously SS's favourite, despite Shakti being the 'obedient' son, and Krishna is still the favourite even though he doesn't have to work, while Shakti has to help with the family business.He probably also has this feeling that Krishna fought to marry Prats and won, but when Shakti said he doesn't want/like Kesar, no one listened to him.It's like a case of being jealous of your siblings. He does love them a lot, but he wishes he had what they have.😆😆😆 And Baba and Komailya got to go on a honeymoon, and I doubt Shakti did 😆😆
