Chester did remember his past life and found out that Yulia was the girl he met after reading the letter she left. The emperor(Yulia's Father) is extremely disgusting, he blamed Yulia for the empress death and used dangerous drugs to change her eye colour and hair colour to match the empress', because Yulia looks like the empress, He only realized he was wrong(trashy) when Yulia ran away and met chester so that is where the misunderstanding came because both original Yulia and empress have bright blond hair. Chester is literally locking Yulia up in his house because he knows she will leave him because they both confirm that each other remember their past lives. I think they have a son, name Dylan.
