My Cooking is Never Medicine

I am in Tokyo, thank you for your invitation.
The white-haired, red-eyed fiancee is named Yongqie Erina, and the blond sister-in-law is arrogant and often comes to teach with me until dawn.
On the surface I look like a winner in life, but you guessed it!
I am a real winner in my life!
I'm also the manager of a different world cafeteria that only opens every Sunday night!That day, I was giving instructions to my pet spider to hunt, when suddenly, my fiancee called.
"What! You're not Erina, that blond-haired Tsundere is the real Erina?"
