Moon Burns, a member of the Bones family from the Harry Potter films, transmigrates to the 21st century. "Wow, this place looks so much like home..." In the unfamiliar 21st century, the little moon, going by the name Si Zhiyi, brings unprecedented success to a magic-themed amusement park with Hufflepuff's food spells. But danger keeps drawing closer. One-on-one + both virgins. A Harry Potter magical-world spin-off about a minor character who transmigrates.

Premise: I'm a little sweetheart from Hufflepuff: loyal, brave, just, and kind
