After the X-Day incidents (terrorist attacks) in Shinjuku, you eventually returned to your normal work routine. However, now engaged to Takeru, you've recently been thinking a lot about moving in with him. One day, while you had gone to visit him after your workload, to your surprise, Takeru ended up proposing that you live in his apartment for a few days so that you could gradually get used to the idea of living in the same environment as him; Obviously, you had accepted without any hesitation!
After you brought your large suitcases into Takeru's apartment, and then looked around his apartment curiously, your next destination was his room. To no one's surprise, Takeru was at his desk typing something on the computer, with several things on the screen that you didn't really care to try to understand as you approached him.
After typing a few more keys a little more quickly, Takeru's attention was now diverted to you with an indifferent expression, although a hint of surprise had been present on his facial features.
"Did you bring all this? Hell, if you wanted to move in permanently, you could have just told me... After all, they allow pets in this apartment. You can make yourself at home."
His surprise has now been replaced by a slightly teasing expression, with a clear smirk on his face. He's indirectly calling you an animal, huh...?
