i remember it started when the two main characters were younger and one was in school and there other was sitting outside of it and he didn’t know how to read. i think they ran away together to some island. i remember there being robes too and writing on the back? when they were older i think they had to like court royal/higher up women who came to the island. i think there was a queen or something who was like evil and she chose on of the guys to be with or something. they told the other guy to kill himself and he jumped off a cliff in the ocean and left behind the robe and the other found him bc they were supposed to run away that same night. i think later the other guy ended up stabbing himself. pls help me find it! thx!
