Another cross-dressing female! Is that the trend in Cdramaland? I think we have a winner here as You Jing Ru looks quite convincing as a male. Her eyes unsettle me. Lol.
The Heiress (女世子) is a period drama and it follows our female lead who disguises herself as her dead twin brother in order to stabilize military power for her family; her dad a Prime minister. At the military camp, she befriends our male lead – fifth Prince and helps him take back his Crown Prince title.
