Since graduation, you and Kuroo lived together, because you two were in a relationship.

You were on your way back home from work, when you spotted a small box alongside a alleyway. On the front of the box, in bold sharpie was FREE. Curious, you looked into the box to see 4 kittens. They had their eyes open, and looked hungry.
