Even from the times of Adam, the word cheat is familiar to us.It's weird when someone did something tedious and we who believed to be decent of him are suffering for that
But I have to say the word cheat is just relative. We cannot become loyal to everyone. While we are loyal to somebody we are cheating some. Yes, believe me, bro. While Adam was loyal to Hawa he was cheating the Almighty.
Likewise, when we are loyal to someone, we are cheating some another with or without our concern. You cannot be loyal to everyone all the time. It's all about priorities.  
For example when your parents are against your love marriage, obviously they will be and that's what Indian parents are made for. When their children fell in love, they act like their children are recruited for Islamic State, NO OFFENSE. And they are bringing disloyalty to the whole family by simply finding someone of their own choice. 

At this crucial point of your life, you have to make a stand whether to live your dream or your parents'. While you are obeying your parents you are loyal to them but at the same time, you are cheating your lover who was waiting for you all this time. But if you are planning to go own with your decision to marry her you are keeping your word with her, that is you are been loyal to her, but you are cheating your parents who bought up you till this age with all their expectations on you.
And the worst part comes into being when a book of 20 pages containing your whole life written by a non-graduated, unauthorized, and sadist of all time and got read by another asshole. And he the uncrowned prince of Indian society proclaims and anticipates that this girl should marry before 23.

F**k man, don't you guys have mercy? A profession to spoil the entire dream of youth!! A profession that makes a huge hype in the market for blood pressure tablets.
So in life decisions, you have to keep priorities. When you are loyal to your friend, you are literally cheating your university.You need to set the priority. Whether you can loyal to your friend who was always for you to buy a cigarette at the tough times or you can serve the dumbass university which was trying to defeat your last minute preparations all the time.
But you have always one more choice, that you can cheat both. And it's the coolest and simple method ever. 
You can walk free without marrying anyone and make a tweet "I don't give a f**k to anyone." 
Likewise you can skip the God damn university examination and watch one full season of F.R.I.E.N.D.S series with a bottle of beer.
