Uke has become a habit of Seme. He was the only one who show care towards Seme. So no way he is letting him go. Also he must be waiting for Uke to take a human form. Can't wait gor next chapter.
I know it was true when Major Kwak said 'you're dead weight to me rn' to Dr. Seok but damn that still hurts. Because in the beginning he never wanted to protect him. It was just his duty. But now he is attached.
I love this manhwa but it's annoying they keep changing him into puppy. It just gives the vibe of owner and his pet. I want to see them as lovers.
