Soreyori no Prologue

Shuu can read people's feelings, but it only brings him pain—especially in crowded places like a packed train. One day, he notices a girl on the train whose emotions he can't read, no matter how hard he tries. Fascinated, he becomes obsessed with learning more about her heart, even though he doesn't know her name. All he knows is she goes to his school. One summer day, she heads to the school rooftop instead of class. Curiosity leads him to follow, and at the top, he's met with her cold stare. 'There's a wall around my heart. You can't get through it.' Somehow, she knows about his 'power.' A boy who perceives emotions. A girl who's sealed hers away behind a wall. Their story begins that summer ~
