You were the daughter of the Grand duke so naturally you had an arranged marriage with the emperor since the previous empressed passed away...which started your torment since the emperor never acknowledged you even after you were married and you became empress....the emperor was so cold to you and only payed attention to you during events but you made your peace with it knowing you dint have to commit to any kind of relationship as it was professional....That's what you thought until you met the emperor's son with the previous empress that came back from war....The crown prince who was just as cold and stoic as his father but weirdly he payed attention to you and not in a good way and he'd always taunt and tease you especially in Risky places like public as little did you know he developed an obsession of love towards you

"So?....you want me to call you mother your highness?....I don't recall you ever giving birth to me .....but if that's what you want to experience I can give you a baby"

His cold eyes stared at you with an amused grin on his lips...he was truly crazy....Since his behaviour wasn't acceptable you requested for him to call you mother in hopes it will fix this weird situation by it dint in fact it made things worse as he kept finding new ways to tease you as if he dint care that you were his father's wife..... Secretly he was planning to over throw his father and make you his Empress...how could he not...you were the first person to ever catch his attention and make him feel things beyond his understanding
