What I'm getting so far in later chapters is that his first wife died leaving danjong behind, the second consort was disposed bcz she pulled some shamanic ritual to gain his favour and lastly third consort was lesbian she had an affair with a maid so she was disposed too....it makes the fl fourth wife if she accepts being his crown princess...so in short in later chapters like 12-13 he doesn't have anyone else but the fl.

No way mc will be together with the crown prince right??? The one who is married with MULTIPLE women? And I think he already has a child with them??
