Kono Naka Ni Hitori Imouto Ga Iru Episode 2

Abiding by his father's will, Shougo was transferred into an academy where many young girls attend. It appears as though his younger sister (separated from him at birth) also attends this academy. She is trying to get closer to him without letting him know who she actually is. Problem is, Shougo seems to be popular with the other girls as well! Can Shougo "properly" reunite with his little sister while getting a girlfriend at the same time?!
