This is why I love Yujin and Hyunjae. They need each other not because of pure interest of their skills. They understand each other deeper than anyone else. Both of them can feel each other's struggle. Yujin need Hyunjae because no one, not even his dear brother, can understand the loneliness he feels all this time. When he is overwhelmed, he needs Hyunjae to calm down his emotion.
Hyunjae needs Yujin because of his relationship with the other beings, the only one who understands all weird things he felt all this time. The only one who has the key to solve all anomalies happening in their world/universe. The only one who can answer his curiosity about all things, including the other. The only one who can guide him back to the right road to home for things that will happen in the future.
