Looksoh doesn't to be on the bottom two ... She's more horrible than Ribbon in my opinion. Sure, Ribbon sold herself to support her needs/wants but she was not all that bad comparison to Looksoh. Looksoh left Ton at the scene to avoid paparazzi, at that point, I would have said she loves herself more than anyone else, she tried to create a problem between two good candidates to get rid of her opponents, she used Ton to her advantage by pushing him to publicize that he's Ribbon boyfriend, and the list can go on.
If I have to declare a winner between these two, I'd say Dear just because she deserves it more than Looksoh with the way she carries herself throughout the show. She didn't get along with Bebe because she feels what Bebe did is unfair. It makes sense why she's doing that and when she knows she can't do anything about it, it's too late. She've been used and blackmailed by Alice so ... she's corner with a decision to protect her friend/turn lover. At least, she's more caring of those around her except the mean one comparison to Looksoh.
Out of all of these people, I think Aeoy and Summer deserves the crown the most because they were there for themselves. They did not cause anyone's any troubles .. the argument Aeoy has with Baikoey was not that severe enough to be called causing trouble too so she deserves the crown. As for summer, honestly, she was so innocent and carefree in here .. she used to do drug but she stop for the pageant so she has improves herself for the better. She deserves to be crown too .. I think she didn't make it because (maybe) her life was not that interesting according to the audience.
