Ask for an American youth movie.

It's been 10 years since the first American school, and three hopeless new virgins have discovered the Book of Love hidden in the high school library. But unfortunately, this book is not complete. With incomplete advice in the book, the three embarked on a funny journey of virginity. With the help of Mr. Lewinsky (the pioneer of the original work), they created a brand-new "Suotian Aishu", which was finally completed and found their own home.
