Uzuki thinks she's an angel and has fallen for a cute stranger. Minazuki can't decide which after-school club to join. And the Annual Field Day is on its way and the competition for Best Lunch is about to commence! All of this would be manageable if one of Chitose's moms weren't intent on taking over the world!

Poor Chistose is stuck in the middle of all the insanity once again. Mama Kisaragi has developed a split personality - as if her regular old single personality wan't scary enough! Kanna is discovering new and faintly disturbing feelings for our hero. And intrepid and terribly confused Fumitsuki has reached the point where she simply must know what Chitose's true feelings are.

What teenage boy wouldn't want to spend his days surrounded by a pack of beautiful women? Chitose, that's who! He just moved out of the orphanage and back into his deceased parents' house. But instead of lounging around the ultimate bachelor pad, he's dodging discipline from his five new mothers! His high school teachers have adopted him, and the only thing that overshadows their good looks is their near-psychotic maternal zeal.

The series you love is back for extra credit! After following Chitose through fourteen episodes of mayhem you may think there isn't any more insanity left. But you would be wrong. And these three expanded episodes of Happy Lesson are living proof!
