Recently released from military service, Hanbin Ryu was aimlessly wandering through life when he was suddenly transported to another world. Unfortunately, his "guide line," or system meant to assist him in survival and growth, contained numerous errors that left him stuck in the tutorial stage for over 20 years. Upon release, he discovered that many people in this new world were hostile towards others like him. As a low-level, super-tutorial newbie, how will Hanbin Ryu navigate this challenging environment?
