I have no doubt that LPB result was Bogus, not only in last episode but also in other episodes. Any person who has some education can't believe that a girl like Rumpa can be Indian Perfect Bride.
If Rumpa is LPB, it means Indian Perfect Bride has following habits:
1- No respect for parents (Just watch episodes after her mom entry and she damn care about her parent's consent regarding her engagement with Hitesh)
2- No respect for colleagues (Just watch all episodes and notice carefully how she got close to different girls at different timings as per her needs)
3- No respect for Hitesh as she said that "waqt lage ga trust ho jaye ga" and claim she is in love with Hitesh
4- No respect for other's feeling (As she said Priyanka cry for no reason and later accepted by stating " Jab apne pe parti he tu runna aata hai"
5- Lie whenever she likes with all confidence (As she said in finale episode that because of her patience and firm comment people will make her LPB, we have an exam of firm commitment with Gurave)
6- She love Bullying (As she did with Priyanka)
7- Love one and marry other one (Hitesh & Gurave)
