Miyazawa Yuya is an average sixteen-year-old student at Sendai High School in Tokyo. He is not a bad student at all, though not top of his class, and is a shy and quiet boy, to say the least. However, his life is far from average; his family life is in ruins, as his family disregards him. His father verbally abuses his younger son, believing Yuya to be the family's shame, further undermining the boy's already fragile self-confidence. His older brother, Hokuto, a twenty-year-old university student, who, according to the family, is perfect in every way, also enjoys physically exercising power over his younger brother. After all, he always gets away with it; everyone believes him.

One day everything changes, when he meets Senda Hiroto, a beautiful and kind university student by accident. However, what Yuya doesn't know is that he is not the only one struggling with pain, and it's a good question whether two emotionally wounded people will be able to heal each other's wounds.
