Yona is the first friend Shin-Ah ever has and also the first person who thinks of his eyes as beautiful[28] and not terrifying.[29] Because of this, Shin-Ah cherishes the name he got from her, and seeks to be someone befitting of his given name for Yona someday.[22] Be it because of the dragon’s blood or his will itself, he cares deeply for Yona and always looks out for her safety, but, for this reason as well, he becomes against the idea of teaching her swordsmanship as he fears that she will get hurt after seeing the first time he lend her his sword.[30] When worst comes to worst, he will not hesitate to break his promise to Ao and will use his dragon eyes even if he loses himself in the process just to protect her. He was shown enraged multiple times whenever Yona was hurt, showing just how much her cares for her and how protective he can be of her like the others.
