Strongest Survival by Otome Game’s Heroine (LN) - Vol 5 Chapter 6: Twisted Event First Part

The countries of Mephius and Garbera have been waging a war for ten years and are trying to put an end to this long fight through a political marriage between the two royal families. Orba, who was driven from his home because of the war and was forced to become a gladiator, looks exactly like the crown prince of Mephius, and it has been decided he will be substituting him during the wedding ceremony. On the other hand, Vileena, the princess of Garbera, has secretly decided to ensnare the crown prince for her own country’s interests.

Some people transmigrate into Emperors, others become wangye.

Li Changtian: “&%%%￥&￥#@”
