Alex wasn't naive. He could discern when someone was tailing him, even if the individual was skilled at blending into their surroundings.
'Who's following me? It can't be the vampire because we're in daylight. Could it be one of his henchmen?' he pondered.
Lacking knowledge about what vampires could do in real life, Alex could only draw from his experiences in the game, where mind control was a possibility. If vampires possessed similar abilities in reality, then the person tailing him might be under the vampire's control.
'What should I do? If he's under the vampire's control or working for him, he could break into my house and destroy the protection symbols,' Alex thought, feeling a sense of impending disaster.
The idea of relocating crossed his mind, but he quickly dismissed it. He was fond of his apartment and didn't want to live in constant fear of the vampire. Instead, he resolved to confront the threat head-on.
