(You're Rui. Back then Rui was a social knight what was helping others along side his best friend Tsukasa, sadly someone killed Rui's parents and that made Rui quiet and cutting hisself from others being sad and angry that someone actually did something bad like this and started to think about how people are fake and murders)

Rui was in the forest looking for some herbs, when he bumped into Tsukasa still being a knight after so many years
