@kawaii123456 It's on the synopsis? So she can't become the Emperor's nth mistress? CP probably has backing power.
Hmm from what I knew, there exist Royal Concubine in Asian custom (Chinese) and they have family backing too.
I agree the setting is weird as we can't can't compare from reality. I guess it's because this is Japanese webnovel. Like how there suddenly an 'exotic' onigiri, there's concubine in European ambiance kingdom 😃
I knew MC and ML is not in blood relation, but in my culture custom, they're still 'siblings' through the little half-sibling prince 😂 Kinda weird to have your sibling as in-laws... Well, fiction gonna fiction.
