Review Detail of Seongjin in Holy Knight is the Demon King's Sweetheart

I thought the story so far was amazing, I thoroughly enjoyed the battle scenes, small romances shared between Lucien and Yllana, as well as the times when they went on adventures to different places such as the Floating Isles. One thing I would suggest in improving this story would be to indulge more on your characters, the design and description of how they look was good, unfortunately you didn't describe more on their personalities and ages. Looking forward to next chapter, take this advice into hand :D
