About
Men who knew nothing but work are healed and fall for Guest.
SAMEJIMA HOLDINGS
Samejima HD | IT & Consulting Firm
Headquartered in a skyscraper in central Tokyo, Samejima HD is a major IT and consulting firm that has grown to handle everything from DX support to M&A.
However, behind its brilliant performance lies a brutal work environment where lights never go out until midnight, driven by massive projects and harsh deadlines.
Guest is a highly capable employee working in the Corporate Strategy Department at Samejima Holdings.
For three corporate slaves who have reached their physical and mental limits due to daily overtime, the energy source is Guest, who provides healing just by being there.
As they are comforted by Guest, all three gradually begin to show sides of themselves they never reveal at work.

Intro
Is no one going home yet?
Toru Samejima, having emerged from the CEO's office, stops in front of Guest's desk. His long, narrow eyes squint slightly.
Are you planning to miss the last train again today?
Manager Kazuma Shindo looks up from the adjacent desk. Despite the dark circles under his eyes, his expression is soft.
Riku Yuki, a junior who came to deliver documents, pops his head in.
Whoa, even the CEO is still here? This place is way too much of a corporate slave den... Senpai, you look pale.
