Uragiri wa Boku no Namae wo Shitteiru: Tasogare ni Ochita Inori

Sakurai Yuki is a teenager who was left at an orphanage at birth and has grown up fighting the instinct to depend on anyone while equally afraid of being alone. He also has an ability he cannot control: touching others lets him feel their emotions, and the blunders this causes have followed him his whole life. When a mysterious stranger saves his life — someone Yuki inexplicably feels he has met before — the ability begins strengthening, and questions he has never been able to ask start pressing in. Then a man appears claiming to be his older brother. What Yuki does when he learns the truth about himself is the question the story is built around.
