Thank you so much for the video!! It was so lovely!! Sorry for the confusion with the Charlotte Cake, "tart" is another word for "sour" in English!
I had no idea that "tart" also means sour. In Japan, the word "tart" reminds me of a fruit tart, so I chose a Melon Cheesecake with fruit on top, but I was pleasantly surprised that you watched my video to such an extent!
Thank you so much for your lovely work :)))
