Wish of a self-proclaimed loner

Our protagonist is Kojou Akatsuki, a quiet, honor student whom everyone looks up to. While he pretends to act like an honor student, and a perfect role model for his little sister, Sayaka, he lives and fights desperately the fears of his past. What he looks on the surface, and what he is in real life are the two sides no one knows about, except Kirihara Hana and Yamamoto Sousuke, the duo he met when he first stepped in the grounds of Setsuna Academy, from where his life changed.
