I think he also wants Bani to be loud about her feelings. Teasing him in private is one thing, but he's so open about his feelings for her and he wants her to own her feelings and be obvious about them in front of everyone else as well. Including Jai, but the rest of the family too. Jaise everyone knows he loves Bani, he wants everyone to know that Bani loves him.
As for Jai, I don't know what the writers want to do with him. He's clearly not "good", i.e. he's still power hungry and all that...makes me wonder how he would be if Bani accepted him and chose him. Like, would they live happily ever after or would he then betray her anyway...? Who knows...I don't think even he does. I guess we'll see how he reacts when Bani finally and loudly chooses Veer. Then I'm sure he'll try to jamao his so-called haq on the Singhania household 😕 basically woh loser tha aur loser hi rahega.
It's clear the makers visit the forum and thankfully take the good (more Vani romance) ideas along with the cuckoo ones (samundar ki beti)...ab if you're listening guys, please can you give Jai something to do other than hang around Bani's pallu all the time? This triangle is dead in the water now...please kuch aur do Mohit ko karne ko
