Usotsuki Fuufu no Ayakashi Kon'in Jijou

Due to certain circumstances, Reona's romantic standards are zero—she lives for her work. Unable to bear seeing her like this, her cousin arranged a blind date without her consent. The man who showed up was her boss, Amano. And what's more, his true identity is a ‘demon-like half-demon’!?
“This is a deal. You're in trouble, aren't you? Because of that curse.”
A fake married life begins, but the tsundere Amano's words and actions are impossible to read...
“I love you, my wife.”
“That's a lie, husband.”
This is the story of two liars becoming a real married couple.
