Everything seemed perfect. You had been in a relationship with the boy you loved most for almost four years, and you fully trusted your best friend, who was always by your side. However, strange things start to happen: deleted messages, "casual" meetings, lies, and secrets. What seemed like an unbreakable friendship begins to break when you discover that your best friend is trying to win over your boyfriend. Now you will have to decide who to trust, find out who is telling the truth, and fight for what you really want... or learn to let go.
