Wife is A Secret Agent

Wife is A Secret Agent summary:

I was a mercenary overseas and I earned myself a code name “The God of Murder”. Still, I need to find myself a wife, at the matchmaking corner! I don't want any gold-diggers, that's why I tried so hard to keep a low profile. But the girls wouldn't accept such a “pauper” like me.
Forget about the low-key, I'm handsome and rich and capable! Of course girls love me!
And then I met a blonde, who decided to marry me at our first meeting…
But excuse me? Did she say she's going to divorce me the next time we meet? I will not let it happen!
