Tonari no Onna no Okage de Itsunomanika Daigaku Seikatsu ga Tanoshiku Natte Ita

Synopsis

University student Sasaki Kento is a loner. However, one day a beautiful girl named Itou Natsuki sat down in the always-empty seat next to him. "This seat is free, right? If you don't mind, can I sit next to you?" With this "chance" meeting Kento's dull black-and-white life started to add a bit of color. (Source: Kadokawa, translated)
