Isn't there a season 2?

The story is so good that I didn't stop to watch it over and over again. Only at the end why wasn't Gaon with Yohan and Elia? They are both lonely people. However, when they are together, they can become family and brothers. Remembering Elijah's condition, he needed support and a family because he also considered gaon as a replacement for his father. Isn't there a season 2 to spoil the ending which I found unsatisfying?
Overall the story is very good and yeah ... still need season 2!
Please give season 2 to this drama!
