I'm the Unlucky Bride of an Assassin!?

If he's going to kill her, the least he can do is grant her wish...

Satori's had a tough life just trying to make ends meet. She's never had a boyfriend, and of course, she's never been in love.
One night, she gets approached by a dangerous man on the street. Right when the situation's getting critical, another man comes along and saves her. He's gorgeous, though he tells her with eyes as cold as ice that he'll have to kill her...
Rather than take her life on the spot, though, he somehow ends up becoming her temporary boyfriend!

Is he really gonna be Satori's first time...?
