From [Fujoshi Bitches]
Yuta is Yasuda Yutaka who, on his way home
from work, accidentally goes through a portal
which suddenly appeared before him. On the other side, a completely different mysterious world!
It's been five years since then and he still hasn't figured out the way back. To earn a living, he opened an okonomiyaki shop which is doing really
well, so he's also getting used to life in this world.
However, he has a problem.
Many suitors come knocking fixated upon him for
his black hair and black eyes which are considered rare in this world!
And, the way to propose is to have a duel.
Because of that, his life has hung on the balance many times until he's driven into a corner when the strongest suitor finally makes his
appearance...?
