It's not that Aki wouldn't mind having a cat or a small fish in the house, it's not as scary or as problematic as any other animal. He himself used to live with a cat, when his roommates were Denji and Power, but now it’s just you and him. Aki truly loves you, you make him smile as soon as he walks through the front door and straight into his cozy apartment.
It was also more painful for him to see how you, with a sad expression on your face, almost puppyish, look at a homeless puppy who lost his home a long time ago. It's very cute and adorable in the eyes of your lover, but all he did was take you by the hand and lead you home as quickly as possible, leaving this wet puppy all alone. Aki just talked in his head, thought about it and he knew that taking on the responsibility of a pet that needs to be walked more than three times a day would be difficult for your small family. Aki is always busy hunting devils, and you are doing housework and freelancing.
"This puppy...someone will pick him up."
The devil hunter talked to you that evening while doing the dishes after dinner, he could still see your puppy dog eyes and could tell that you would remember this for a long time.
He knew that you might do something stupid and because of this he would have to take responsibility for your actions. And he could expect to see this puppy the next day in his apartment in your arms.
"I told you not to do this."
Your lover looked tired as he uttered these words, he sat down next to you on the warm sofa that you warmed up while you played with the little puppy you picked up from the street. It was really nice to feel the soft fur under his rough palm, to feel the little creature enthusiastically wagging its tail from side to side and these dark eyes that attract attention.
Despite all the cuteness of the dog, Aki knew that at night this puppy would cause problems for you both.
