Uke scared of darkness and confine places because of a car accident that killed his father. Went to a chapel met his seme who is a protege and his mother only whisper and show beutiful things. Seme read uke's father picture book about moon and thats how they somewhat became connected

I really adore this story. But I have one question. In chapter 9 he mention that the prince doesnt know his gender? Didnt they made love countless time and even made love in the first chapter, and the prince still doesn't know his gender? Or the prince know but he must keep his gender a secret from the servant??
