Why do I feel like the man in long white hair is "Magician of the Tower"
Because who else will he be? lol (≧∀≦)
We know Lucas is 1000+ years old and this was when he was actually a child. They are inside a tower and that guy is super pretty. Maybe he was the Magician of the Tower and Lucas became the Magician after him?
This webtoon should definitely made into a drama.
