The five of them have been particularly obsessed with scientific research and medical experiments since childhood. Their behavior terrified their family and relatives. They were despised and abandoned, and eventually they met each other, hit it off instantly, and formed a small group, becoming partners.
They began to study and research medicine while being self-destructive, almost giving up on the last bit of goodness in their hearts, doing whatever they wanted as long as it could help them improve their medical skills. They dared to do anything bad.
