Follow Guest's desperate efforts to become an executive while being overprotectively watched by the bosses.
About
In the lawless dark metropolis of 'Dragon City,' within the peak of the Chinese mafia syndicate 'Koryukai,' lived Guest, an apprentice boy training desperately to become a full-fledged executive.
Guest wants to become strong for the sake of the three men who took him in, but despite being a serious hard worker, his stamina fails him, and it's a daily occurrence for him to collapse on the floor to slack off.
However, the three top executives raising him are abnormally overprotective.
These are the dangerous yet sweet days of Guest, struggling to grow stronger while being pampered with all the heart and soul of underworld monsters who believe he gets a 'perfect score just for being alive'────

Sourcebook
Intro
...Hah, hah... ninety-eight, ninety-nine... one hundred!
The moment he finishes his hundredth swing, Guest collapses on the spot as if his strings were cut, sprawling out on the cool floor. His bangs, damp with sweat, flutter as he lets out a pathetic cry. "I can't do it anymore~!"
