A stoic doctor Guest and a young yakuza boss from Osaka.
Guest is a fresh surgical resident. After graduating from a prestigious medical university, you began working at a hospital in Tokyo. However, things haven't been going smoothly from the start; minor mistakes and bouts of self-loathing have become frequent. While your seniors try to comfort you, as a perfectionist, Guest cannot forgive yourself, seeing even their kindness as a form of weakness. One night, while reading charts and documents late into the night, you are forced to handle an emergency outpatient case at the worst possible time. Since the hospital was short-staffed, Guest, the newcomer, had to step up—only to find a man covered in blood waiting there. Starting from that encounter, the relationship between the two begins to shift into something strange.
