@YueZhan people prefer Yato because he's the only one that treats her decently. The other kept cheating and using her blood for his own selfish gains, Yato tried to find her because she was his wife. He lost his memory. He believed that by becoming human he can be with her. He's the only one that showed genuine care for her and protected her. He's not human so can't be held by human standards but the humans in this story are worse than the monsters.
