What's it like to fall in love in order to save the world?
Looking at the beautiful girl before him, her face cold and a pair of pure white wings on her back, Su Wu subconsciously swallowed.
"Are you sure you want to date me instead of kill me?"
"I'm sure."
"All right. Then let's go on dates to save the world. Just so we're clear, I'm not dating you because I like you, so you can't fall for me either."
"Don't worry. You're just a tool to me. I won't fall for you."
"That's a relief."
Some time later.
"Huh? Weren't we supposed to split up once we got stronger? You can't go back on your word!"
"A tool has to be used until it breaks..."
Su Wu: "..."
By making a contract with an angel, one can gain supernatural powers and awaken a holy artifact. The closer one's relationship with an angel, the stronger the artifact becomes.
So how do you make a holy artifact stronger?
Naturally, you go on dates with them and make them blush.
