Yuki has spent his life as an orphan at Asahi, desperate to prove he doesn't need anyone's help. He carries a strange power: every touch lets him feel someone else's emotions and glimpse the pain hidden in their hearts. Yuki can't control it, and his attempts to comfort others often end in clumsy, hurtful mistakes. Anonymous notes telling him to die begin to arrive just as his ability grows stronger, and unknown people are watching him, some meaning him harm and others wanting to protect him. One foggy night a striking stranger saves his life, a man Yuki has never met who somehow feels familiar. Then a man claiming to be his older brother appears, and Yuki's forgotten past starts to surface. What follows is a fantasy drama about a boy piecing together who he is and where he comes from, while making friends and facing betrayal.
