Rachel will hurt you.

"Good that you are trying to understand me, Athena... But, always remember that this world is so cruel... So, can do anything for themselves and be selfish... But there will be only person who you can trust the most in this world after your parents and that is your loved one..." Dean said as he looked into her eyes. 

"You would even don't believe the friends who you had been with for 20 years but you will just trust your loved one in just months without knowing anything... Because you believe in him... And wants to see future with him. But you would have no idea of those friends who had been with you for 20 years but not sure if they will be with you in future but you know that, the guy who you love and wants to marry him would always be with you!" Dean said as he took a deep breath.
