A brief description of the Bokutachi wa Benkyou ga Dekinai manga:
The disciple Nariyuki Yuiga comes from poor backgrounds with a single mother and three younger siblings. He is therefore all the more delighted when the school’s director offers him a university scholarship. In return he has to give three geniuses extra tuition to the school. Fumino Furuhashi is a literary genius, but a loser in maths. Rizu Ogata is a genius in mathematics and natural sciences, but is hopeless in humanities. And last but not least, Uruka Takemoto is a sports genius who fails in all other subjects.
