Goshidou no Hodo!

In this world, people are separated into the following genders: alphas, betas, and omegas. Yukihiko Fuyukawa is the successful, strong, and strict manager of a leading sales company. He is good looking, kind, and rich; the perfect package. Everybody swoons in his presence. On the other hand, Natsume, Fuyukawa's subordinate, is weak, sad, and disorganized. He often makes mistakes and has to make up for them by staying late in the office. One such night, Fuyukawa was waiting for his last subordinate, Natsume, to finish his tasks. Suddenly, something utterly dire comes to light: his suppressants have run out! He is in danger! And just as he thought his luck couldn't get any worse, the man he wants least in the entire world, decides to... BOND with him! We repeat: he is in danger!
