The truth is Max was aware that Chleo was watching his every move as he put Chleo's suitcases into his trunk. In his heart, he was happy because it turned out that the girl adored him as much as he did.
Moreover, he had a secret that he couldn't say to anyone. A rather disturbing secret and maybe… would make a girl's view of him change.
Ever since he had a love affair with the girl, he would come to the girl's room almost every night just to look at her sleeping face. Does that mean he's officially a stalker? But he couldn't help it.
As a ruler of nature, his feelings when falling in love are beyond no word. In fact, many times stronger than true love known by ordinary humans.
Maybe that's why Katalina, the previous red queen was able to sacrifice her life to save her lover. Rulers of nature who could only fall in love once in their lifetime would not be able to live alone in this world when their partner was gone.
