After losing his parents, he yearns to become a Knight, the poor boy Wynn Byrd diligently trained himself. However, it was hopeless for him to become a Knight, because his magical power was too low, he can’t pass the Knight examination so he was labeled with the unpleasant title of 『Eternal Knight Cadet』. But one day the Hero defeated the Demon King and saved the world. The Hero was a peerless beauty and she gained attention from the entire world. However, the Hero declared to the world. 「I will return to my Masters (Teacher) side, Wynn Byrd.」 This is the story about a boy who somehow changed his class from 『Eternal Knight Cadet』 to 『Heroes Master』. When this post was made there were 9 chapters So in the latest chapter when you see Wynn with Leti I thought was so sad. Although Childhood friends he recieves scorn from just hanging out with Leti. It really made me sad that I felt like crushing a hole into my tablet. I wonder when it will be revealed that Wynn is Leti's Master. I especially wonder whats going to happen next as well~ I even more wonder how Leti will react to the sudden change of the way Wynn treated her~ Ah sorry I'm just going on and on but I really like this novel so thats why I made a latest chapter discusion.
