No sadly he won't remember her 😭
Yuvaan ka trauma theek hone ke baad he'll forget her and isske baad mostly separation milega. After he comes out of trauma Yuvaani ki love story will start till then they'll be besties. Shaadi ke 6 months ya ek saal baad hi Yuvan theek hoga.
What I think is ki according to itv logic the very moment which gave Yuvan this trauma will bring him out too like. Him and Banni will be performing some pooja when Banni will be going to have the same accident as his mother but this time Yuvan is successful in saving her life and this very moment he comes out of his trauma. Usske baad Yuvan ko sirf apne gharwale yaad honge, he'll forget who Banni was. Maybe he'll remember the taste of her food and will miss it but usske alawa he won't remember her. Dadusa and Hemant will let him know who Banni is but he'll be just cordial with her and not behave like a husband. Iss track mai mostly separation mil sakta hai.
Yaad hai jaise Barrister Babu mai Anirudh and Bondita fell in love after she became an adult and then we got a proper love phase of theirs the same way when Yuvan gets normal in future usski aur Banni ki love story shuru hogi.
Meko toh ye bhi lagta hai ki Yuvan ke theek hone ke baad pura Rathore Empire usske naam pe hoga.
