lolz its alright his actions are deceiving
Udayveer is a prince himself and his family has been family friends to THE royal family for generations.
When he was young as in a child he was engaged to Manyta but then she got kidnapped. However he has been waiting for her for 16 years just like everyone else was. But being engaged has never stopped him from being a ladies man. He has a sister Unnati and she is the only person who can take truth out of him and in front of whom he can't pretend and he obviously loves her a lot.
Jainandani is Manyta's sister - she has a crush on Udayveer (i don't blame her he's a oh-so-drop-dead-gorgeous) and she has always been jealous of Manyata because even thought Manyta was never present in Jai's life physically everybody always kept Manayta present in their memories.
Anyhow Jai was getting engaged to Uday but then they found Manyta and so naturally Udayveer said now that my long lost princess is here I ain't getting engaged to anyone else. which has pissed off Jai even more.
Uday flirts when Jai because its fun for him but he's intrigued by Manyata and how she behaves.
Him and his father wants to marry Manyta for money but the way he remembers his childhood with Manyta and the way he merely just looks at her we all know he's gonna fall head over heels for Manyta. Also he puts up a face in front of everyone that he's more interested in the money than the marriage but really what his true intentions are we don't yet know and that's what makes him even more HOT!!! so there that's a brief of Udayveer
