This is the professional debut for doujin circle riffraff, featuring a remake of their doujin title Renai Katei Kyoushi Rurumi. Early April is the start of a new school year, when new relationships and new lives blossom. However, Ayuhisa spends his days in his room and doesn’t even go to school. Of course he hasn’t had a girlfriend before nor even held hands. One day, a private teacher of love Rurumi appeared at his door with the goal of bringing him out of his hikikomori state by restructuring his lifestyle, teaching him about fashion and even lessons about girls. Then Rurumi’s rival Mana shows up along with his non-blood-related imouto Shizuku. And how will he react to a beautiful oneesan that he met online Honoka and an ojousama Chieri? Let the private lessons of love begin! [From Hau~ Omochikaeri!]
