After Successfully Clinging to the Imperial Uncle's Coattails

Lanyu transmigrates into her own comic. She becomes a short-lived princess destined to die at the hands of the great villain... To stay alive, she has no choice but to win over the male lead, Li Sheng'an, and cling to his powerful support. She swears she has absolutely no impure thoughts about that older man. But suddenly, a certain man grabs her and mutters to himself... "Woman, do you know that anything this prince sets his sights on is bound to be mine!" What does that have to do with me? "Woman, do you know that before, my heart held nothing but power?" What does that have to do with me? "Now, my heart is filled with you..." Huh??? Did he just confess to me, or is this some kind of scheme?
