Synopsis by Cammila Collar
This three-episode OVA series concludes the plot of the Happy Lesson TV and Happy Lesson Advance storylines. Mitsuki learns that the old high-school building is about to be demolished so that a new one can be built, and everyone is saddened at the thought of losing a place with such sentimental attachments for so many. Soon Mitsuki, Chitose, and the other "mamas" are hatching a plan to prevent the demolition. As the Happy Lesson tale draws to a close, characters might just come to realize their true feelings for each other.
