Naotaka Takimoto became alone with his younger brother Itsuki due to the sudden death of his parents.
When they were young, their parents remarried and became a family for 18 years. Itsuki lived like a real brother, but he secretly had more feelings for Itsuki than his younger brother.
Although they are not related by blood, Naotaka does not want to lose Itsuki, who is the only family left. I swear to my heart that I will not tell you for the rest of my life.
In the midst of this, Itsuki's attitude became distant from the end of his parents' funeral.
