Rin is the adopted son of the Todo family, a family of exorcists. This gentle and beautiful young man has an unusual relationship with his younger brother. They are both people who are unwilling to express their thoughts. Sometimes the relationship between them is as intense as fire, and sometimes as cold as ice. It is very hard to guess their hearts. In the face of ethics and morality, can family and love have both? Two people are looking for ultimate happiness in a seemingly ordinary relationship.
However, things are getting more and more unsatisfactory. The ghost claw marks on Rin's back inadvertently reappear, and the head of the Todo family behaves more and more weirdly. The dragon ball he has been looking for for many years unexpectedly appears... In this family that is said to be cursed, can he bring an opportunity for happiness?
