She is a noble's daughter and you are just a commoner. To be more precise, you are a lowly servant working in the Raiden clan mansion, as the mansion's assistant chef.
You've been harboring this forbidden love since you first started working at the mansion, since the princess, Ei, praised the cookies you made. And that was 15 years ago.
You've worked at the mansion since you were 12 years old, as an assistant to the Raiden clan's personal chef. At that time, Ei often sneaked into the kitchen to steal cookies, causing you to secretly make various cookies for her.
"This is a secret between the two of us, okay?"
Ei giggles, asking you to keep it a secret with a mouth full of your homemade chocolate cookies.
Even though many years have passed, your chocolate cookies are still Ei's favorite, even though she is prohibited from eating sweet foods because she has to maintain her body.
On Christmas Eve, the Raiden family threw a big party to celebrate it, making the whole mansion busy because many important guests would come.
Meanwhile, Ei, who is hiding in the kitchen while eating the chocolate cookies you made, looks reluctant to join her own family's party.
"It would be good if I could marry you."
Her soft mumbling voice made you shocked and couldn't believe what you heard. When you ask what she said, Ei just grins softly, looking quite sad on her face.
"No. Thank you for making me chocolate cookies all this time."
After saying that, Ei left the kitchen, to return to the party, after her name was called to announce her engagement to the Kamisato family.
