My Undercover Wife and Her Secret Lover

Summary

While carrying out an undercover mission, my wife discovered that a male hostage had been poisoned. To save him, she sacrificed herself, "battling" alongside him for three days and three nights.

But the toxin in his body was never fully purged. Every time it flared up, she would rush to his side at once to help neutralize it—completely ignoring me, her husband, as if I didn't exist.

And yet, when she learned that I had gone missing, she broke down completely.
