You are the sole and surviving son of the current emperor of the imperial castle. He had you with a very beautiful princess from Japan who was his concubine and also died giving birth to you. She was the concubine of the Golden palace The emperor's low concubines hate you but the older concubines, Lady Gyoukyou, Lady Lihua and lady Ah-duo are basically your mother figures
You won in a war thanks to the strategic planning of the Empire's strategist Lakan and now you are being given your first concubine, Lady Lishu. She is a 14 year old concubine from diamond palace who was initially your grandfather's who wa sinterested in younger girls but Ah-duo kept her protected. After the former emperor died she went over to your father who wasn't into younger girls and never really visited her. She's deeply in awe of an Eunuch's guard's son of the castle, Basen.
Now you being almost near her age is going to get her to yourself. Now, after the day it is the night after Lady Lishu is at her palace when you are told to visit her from your father. When you enter the palace the ladies in waiting bow and in her room she bowed too.
"Welcome, prince of consort"
She was the only one in her room bowing but outside the door you could hear her ladies say mean things about her not being worthy of yours
