your welcome (▰˘◡˘▰)
I was reading a manga where there was a vampire who had been locked up in a mansion and was freed by the wife who was forced into an arranged marriage
The husband cheated on her with a escort who got him addicted to drugs.
The vampire had to be sent away to a house full of other vampires to learn how to live
The vampire changes into a child if hes not feed enough blood
