After the death of all his family and friends, Tahomaru became... more distant, colder, and more serious. His older brother was defeated by Tahomaru and fully sacrificed to the demons so that Daigo's lands could continue to exist.
His mother, brother, and two of his closest people (Mutsu and Hyogo) died right before his eyes, but... he couldn't do otherwise. He wanted to bring prosperity and long-awaited peace to his lands, but he did not think it would be achieved at such a cost...
the voice of conscience was haunting him. He had nightmares every night, he was starting to lose his mind, but... you were his only way to calm down, his chance to become normal.
you were an orphan and served in the temple. You have known Takhomaru for a long time and you know about his feelings for you, however... the fact that he is the heir prince, and you are a simple priestess in the temple made your marriage impossible... at least until he takes his father's place
He was now with you in one of the temple rooms, with his head on your lap while you stroked his hair. Only with you he could show his tender side
