My Fiancé Is Not an Ordinary Office Worker

I, Rina Hayakawa, have a very simple ideal. Ordinary struggle, ordinary earning, finding an ordinary office worker as a husband, and giving birth to ordinary but lovely children. After unremitting efforts, everything is developing as I expected. But! Lately... I've noticed something strange about my fiancé. Why? What do you think is strange about him? They are probably hard-working office workers who have suddenly become a little depressed recently, often staring blankly at a big knife I have never seen before. Plus… A man with white hair and eyepatch suddenly came to my door. "Ah~ first time we meet, Nana Ming's wife~ I am Nana Ming's little~ lover~ oh~~" Everything is developing unexpectedly... I… Being cuckolded? ! The target is still a man! ! ! Purpose: Love the one you love and never regret every choice you make
