I've read 'Versatile Mage' twice now, and harem elements are definitely present but not overwhelming. The protagonist Mo Fan attracts several love interests throughout the story, each with distinct personalities and roles. You've got the childhood friend Mu Ningxue who shares deep history with him, the fiery Tangyue who brings out his competitive side, and other female characters drawn to his growing power and unconventional methods.
What sets it apart from typical harem novels is how the romantic subplots never overshadow the main magical battles and world-building. The relationships develop organically alongside Mo Fan's progression as a mage rather than being the central focus. The author balances action, comedy, and romance well enough that even readers who dislike harems can enjoy the series for its creative magic system and monster fights.
