Dazai was a sultan and a very powerful and intelligent person.

Chuya was brought to the palace as a concubine and the fact that a man was as beautiful as a woman made the other concubines jealous.

Dazai spent more time with Chuuya when he saw him. They ate with him, made plans, and spent a lot of time together.
