I read in some article (here is the link http://en.wikipedia.org/wiki/Manoj_Bohra ) that manoj is obviously very different from the character of UD.
For e,g he is not into smoking, drinking and he avoid junk food, he into meditation and likes healthy food and is family oriented person.
Unlike Yudi who is a very carefree guy, too much into parties, girls, alchohol, smoking and never respected elders and not at all family oriented guy.
