That was until a hero deployed by the king who goes by the name Drek joined them on there journey, the long journey seems to be getting to Heleya physically but not because she's exhausted. It seems she can't hold back anymore. (Inspired from a doujin I've read before.) A netorare story. Read to see how everything turns out.
