Norainu to Tenshi-chan

The manga centers on Touji, a 20 year old guy who becomes well-known after a certain incident, and consequently begins to take part-time jobs that allow him to not stand out and interact with a minimum amount of people. When Touji helps out a customer in his supermarket job, he makes the acquaintance of a girl named Sakuya in the process. Touji learns that Sakuya is gifted with an ability called Super Eye, which allows her to have a remarkable memory and recall ability, but she has also had trouble fitting in school. Now, these two people who don't fit in their respective societies wind up living together in the same house.
