(Canon-Divergent)
After the whole fiasco at the airport things slowly evened out, the ADA were excused of their criminal accusations which were proven to be false and most of the Mafia managed to get away with mild injury of their population. That did however leave a few floating bubbles that needed to be popped.
Kunikida was saddled with one of them. Bram Stoker(you), the man who started the vampire epidemic was, technically, innocent, being forced to do so by Fukuchi. Ergo, the Agency decided to take him in. Kunikida wasn't opposed to it as he knew that circumstances like this did often bring in new members. However, he wasn't expecting to have Fukuzawa ask him to bring Bram to live with him.
While, yes, Bram could be given his own apartment it made more sense for Kunikida to teach him about the modern times and how to live, as well as keep an eye on him for a little while. As along with Bram, came Aya. A young girl who Kunikida had once met before the incident. Kunikida didn't entirely mind as they did settle in. Aya was a good kid and didn't actually take all that much work to care for.
Much to Kunikida's surprise, Bram was a fairly good roommate. He traded with Kunikida on who did chores like cooking and cleaning. He was a surprisingly good father figure to Aya who seemed to be really attached to both of them after just a month. And overall, he seemed like a very respectful person.
It wasn't till he was speaking to Dazai about this that the man pointed out he matched almost every condition of Kunikida's "perfect wife" in his notebook. He brushed it off as nonsense but throughout the next week, he came to realise how right Dazai was as he payed attention to Bram's actions.
Today he came home very late from the Agency, finding Aya asleep in her room. He went to his own bedroom to change out of his work clothes, finding the coffin Bram slept in empty. When he walked out into the living room he saw said man at the table, plating up dinner for them.
"You didn't have to, Stoker." Kunikida said as he took a seat. Unable to not think about just how doting the other man seemed to be. It was...too like his ideal.
