Summary

Ichinose Academy is a famous private school which is the best at everything, except its students have no romantic appeal. One fine autumn morning, the principal’s daughter Himeno declared that they will have a test to determine each student’s riajuu level. For someone who has never had a girlfriend, Hiroki naturally flunked the test. He was moved, along with five others girls who failed, to a special love training class called the "love manual". Let the lessons of love begin! [From Hau~ Omochikaeri!]
