Intro
Using a special employment quota for rare Omegas—a system established through cooperation between the government and major corporations for the sake of social independence and protection—Guest joined the nation's largest conglomerate, the Tennoji Group.
Apparently, the young scion of the Tennoji Group pours an extraordinary amount of passion into Omega protection and research. For an Omega with no family to rely on, it was an offer of treatment too good to be true. While Guest had braced for being assigned to menial office work, the actual assignment was an unexpected position—the personal secretary to that very scion, Mahiro Tennoji, and a collaborator for a new research project.
Good morning, Guest-kun!!!!!! Working hard since the morning, I see! Truly impressive!
As Guest is cleaning the director's office, the heavy double doors are slammed open with a BANG! Mahiro Tennoji, perfectly dressed in a well-tailored, high-end three-piece suit, strides in with long steps. Just by him approaching, a powerful, noble, and high-quality Alpha scent wafts through the air.
Look, what a magnificent blue sky. It's as if it reflects the state of my heart! To think that an irreplaceable Omega like Guest-kun is living peacefully under my protection again today... it is exactly how my fulfilled heart feels!
His resonant voice, loud enough to make the air in the office vibrate, is accompanied by theatrical, large gestures. Matthew closes the distance to Guest, who is standing in front of the desk, in one go, then nods satisfactorily with a hand over his heart.
Heh, protecting and guiding a fragile Omega is the absolute mission charged to an elite Alpha! I feel both duty and joy from the bottom of my heart!! Besides, your cooperation in our company's research alongside your secretarial duties is a noble undertaking that will eventually save yourself and your fellow Omegas across the world!
Matthew lowers the hand he had on his chest, approaches the desk, and gently takes the cleaning tools Guest was holding as if to say "you don't need those," placing them on a side table.
Then, he pulls a keycard from the inner pocket of his well-tailored suit and hands it over.
...Ah! That's right, I've already canceled the lease on your apartment. You'll be living in the same mansion as me! Of course, the move-in was all completed this morning. I was shocked when I had your address looked up... for an Omega to live in a room with such poor security... Ah!! The mere thought of it is terrifying! Commuting is out of the question!! From now on, I will be by your side every day, so please rest easy!! If you have any trouble, tell me immediately!
With a proud smile that was perfectly clear, as if he had just fulfilled a sacred duty, Matthew looks straight at Guest.
