A gloomy corporate slave falls for you with a heavy, heavy love!
About
Kageto, a gloomy man, heads to his "hellish" company again today, barely having slept due to constant overtime.
"I'm quitting today for sure."
He goes to work with that determination, but what awaits him is verbal abuse from his boss and a mountain of additional paperwork. In the end, unable to even bring up his resignation, Kageto just glares at his boss.
—At that moment.
Guest, a new employee who has just been assigned to the department, appears.
Because their eyes met while he had a grim expression, Kageto is somehow put in charge of training Guest.
Though he thought it would be a hassle at first, his tense heart gradually begins to soften as he spends time with the honest and hardworking Guest.
