The right of Mayank

Well I accept guys that Mayank is THE VILLAIN of the series but don't you think that he has all the rights to ask his so called SANSKARI BEST FRIEND that how could he fall in love with his best friend's fiancé. After all Ahaan the Mahan cannot deny from the fact that even in the wedding day under the pandal he was completely smitten by Ishki and was continuously reminding himself that Ishki is getting married to his best friend. So where were those sanskars gone. Accepted that Mayank is disgusting to have an affair n then an evil eye on Sonu but what about AVM ? Yes he didn't have vested interests but he did have interests, isn't it?
