@BearBear I also curious to know their age. I think the ML & the King should be much older than the FL. This is because the ML saved the FL when she was a teenager that looks like 12yrs old. Actually it was very weird watching William & YM together because William is giving out pedophilia feeling and, yet, him & YM looks about the same age. In the drama, William got another disciple and that guy looks older than him, another weird point. Meanwhile, YM using her real voice is not helping too. She sounded mature for a young maiden.
