Someone might scold Elennora if they saw what he was doing to Levan.
Why didn't he tell Levan the truth? Why did he keep it a secret even if Levan said that he would still accept Elennora no matter what happened?
Levan did say that, but Elennora still felt insecure in his heart. He thought that it would be easy for people to say something, even to make some commitments, but it would be difficult to do as they said.
Making a promise was easy, but it was easier to break a promise.
Elennora didn't want to see Levan negatively, but that was just his way of protecting his fragile heart. For eighteen years, he lived in a cycle of lies because of his parents, and when he finally found the truth, it was also difficult for him to accept it.
Elennora looked at Levan from that perspective. While he also found it difficult to accept his identity, the brown-haired Crown Prince would probably feel the same way.
