Two lover's in a distance and get back together after 3 years. They've been together for almost half of their lives but 1 mistake ruine everything they have. Yes he/she's your friend ever since but that doesn't mean that you will trust her in all aspects. In all means you have to be cautious of every persons around you whether it is your family or not. It's better to trust yourself instinct than anyone else. They might have bring you pain when the right time comes. Don't be cover of "friendliness" she have. Be observant at all cost, you might have regrets in the end if you just ignore your instinct. Just be reminded that instincts is the most appropriate and trustful thing that you could ever do to your self. Don't let bygones eats you.
