I Discovered the Affair Partner Is My Wife

1

My private detective agency received an order,

To investigate Fintan's extramarital affair.

While tailing Fintan, I discovered the person he was cheating with was none other than my darling Serenity.

Heartbroken and disillusioned, I decided to accept an invitation from a foreign mercenary organization to join their detective squad.

I had been anonymously donating blood to Serenity for 7 years.

From now on, I would no longer need to be her blood bag.
