Don't Make a WishDon't grant my wish brother; Don't Make a Wish to my brother; Đừng Đến Xin Điều Ước Từ Em Trai Tôi!; 不要向我弟弟许愿

I was an only child, but when I woke up, a younger brother appeared. Even more frightening is that this younger brother can unconditionally grant any wish... for a safe life, for the sake of world peace, as his sister, I sincerely advise you to not to make a wish to my younger brother.
