Xiao Yuan, the ace mage of Layton Academy.
After his girlfriend betrayed him and cheated on him during the Alliance Championship Finals, he lost everything and fell into despair.
Ten years after vanishing, he returned to a world that had moved on. Hiding his identity, he re-enrolled at his alma mater as a mediocre student, quietly protecting his younger sister, Xiao Lulu.
"You want to be my brother-in-law? First, let's see if my fists agree."
"Hah, I'm taking Lulu to the amusement park. You have designs on my sister, so why shouldn't I beat you up?"
"Lulu, don't walk so fast. You might fall!"
"Just say the word, and I'll pluck the stars and moon for you. I always keep my promises."
Xiao Lulu: "...Bro, that's enough."
