When Lara receives a package full of letters in the middle of moving, her life stops. Everything ceases to matter: the move, her impending wedding, the beginning of a new life. Eliott, her first love, who disappeared ten years ago, returns as the sender of a shipment that will fill Lara's heart with memories that she thought were forgotten, and they resurface from the past with force. Her life will teeter between the choice of a stable future with Harvey, the wonderful man with whom Lara has remade her life, or that of an entirely uncertain destiny.

There are friendships that appear at first sight like arrows in the heart, sometimes friendship turns into love, and very rarely, a part of that love ends up being eternal.
