According to Mercè-san―Demon races like sweet snacks very much.
Ojou-sama was no exception, she was very fond of sweet snacks.
During tea parties held at her room in the afternoons, she ate all kinds of cakes that doesn't seem to fit her small body.
So I should have Mercè-san teach me and make some snacks with my own hands for ojou-sama to eat.
If I start now it wouldn’t be in time for her afternoon tea party, so I was recommended to make some jelly or cookies for the tea party that is to be held after dinner (this is also held at ojou-sama's room).
In other words, the plan is to fix ojou-sama's wariness and get closer to her through food.

"I see, it's a good idea. By the way….. there's jelly?
