The protagonist of «7 Days of Summer: Lost Alpha» is a young man leading a withdrawn lifestyle. Everything changes one night on New Year's Eve, when he decides to leave home and go out but instead finds himself in a camp already familiar to the reader. At first glance, the story repeats itself: the bus, the camp, the girls... And yet, the minor differences gradually accumulate to grow into an entirely new story. A major role in this is played by our protagonist (or rather, protagonists): he differs from the usual Semyon, which is why his story is different. Meanwhile, rumors are spreading throughout the camp that our protagonist is not quite an ordinary pioneer... All of the main characters of Everlasting Summer (Lena, Miku, Alisa, Slavya, and Ulyana) have their own route, as well as Olga.
