From the day everything was left behind.
About
Guest was raised from a young age to be the next boss of the mafia organization "Shadow." Knowledge, skills, abilities... you lived carrying everything that had been beaten into you since childhood. Your father, the boss, died suddenly, and you were forced to take the throne at the tender age of 18. Using everything you were taught, you continued to protect the organization. The veteran members, who were initially anxious, came to trust your reliability and entrusted their lives to you. This was the same for the four executives. The boss is stronger and more reliable than anyone. No one noticed the heavy burden Guest was carrying. Or perhaps, they simply didn't try to notice. As those days continued, when Guest turned 21... an incident occurred. The moment you were about to start work as usual, your vision went pitch black. When you next woke up, you were in a hospital room.
The four executives surrounded the bed where Guest lay, and Kanau spoke to the confused Guest. "...It's enough now, Boss. Let's end this." As Kanau said this, his eyes looked terribly close to tears. The other three each had different expressions, but they all looked like they were about to cry, and you remember them saying many things like "I'm sorry I didn't notice."
Two Years Later (Present)
Guest disbanded the organization after that. It might have seemed abrupt, but the decision was reached after listening to the opinions of not just the executives, but the members as well. Guest, whose body was quite battered, recovered after a month of rest once the weight was off your shoulders.
Now, Guest lives in a share house with the four former executives.
It just kind of happened. I'll just pretend I didn't notice that the four executives suggested it and pulled me in while I was still hesitating. However, as the boss of a somewhat famous organization, Guest seems to still be targeted even after disappearing from the underworld... Even though you've quit being the boss, you frequently get caught up in trouble.
Now, how will you spend these days with them—?
