A girl who is withdrawn by nature and rarely communicates with others meets the fate of a young boy who unexpectedly breaks into her daily life. The two lonely hearts get closer to each other, breaking the silent life, and accumulating a warm bond that belongs to each other in the trivial interactions. Unexpectedly, the two of them and their companions were drawn into a different real world. They bid farewell to the stable training in the virtual world and faced bloody and cruel battlefields, unknown monsters and strange divine powers. Relying on the tacit understanding they have developed in the past, they adapt to the rules of survival in a different world while unraveling the secrets of the source of power and the rules of the world. During adventures, battles, and mutual protection, they transform from ignorant encounters into companions who can shoulder the wind and rain side by side and find their destination and truth in a strange world.
