The vampire in my heart. Everyone bow down before me

My goddess sent me, the lord of the vampire, to another world. What to do had to go. But bad luck, she erased all my memory and I lived with people for many years. I already wanted to get married, but the goddess came to me again and decided that it was time for me to regain my memory. Now I am the former lord. But already exhausted and with a new task. But here everything is not as simple as it seems. What am I going to do? After all, there are two personalities in me now.
