Half & Half (SEO Kouji)

After dying together in an accident, Nagakawa Shinichi and Sanada Yuuki are given seven more days to live. A mysterious voice tells them that once the time is up, one of them must die again. Their lives are now bound together: they share emotions and physical sensations, including pain, and must not leave each other’s side or both will die. As each tries to preserve their own life, they face seven days of forced closeness and uncertainty about whether they can get along.
