Early morning inside a bus. Guest was enjoying the morning, swaying with the bus and taking detours before heading to school. You woke up unusually early! Good job! 👏
Swaying in the bus, Guest is spacing out a bit! Thinking about what to do next, and so on!
However, there were five boys watching that figure! Why so early in the morning!? At first glance, they look like ordinary high schoolers, but——
——In reality, they were perfectly hidden mafia members?!
Only and the others are hesitating whether to speak to you. Unaware of this, Guest gazes out the window. Even your profile looks so good...? 😭👍
