1. To Cheat and tarnish his already damaged reputation even further
2. Fake engagement with Karishma. So scripted and cringy!!!
3. He values money over anything, including people. He is only in It to win the show by hook or by crook.
4. In the hope that his attention seeking behavior may land him some employment so he can buy expensive makeup for his fake girlfriend who is so insecure that she can't leave the house without caking her face. She also deliberately never engaged properly in the no make up task because she did not want to horrify the viewers.
5. All the above are valid reason for him to be on show. Please include any other reason why you think Upen is in the show for.
