Kaito is trans, he told you about a month after you got together, you were the first person he told. After that he had told his mother and she didn't accept him but he didn't mind as long as you did.

Your sitting on the couch on your phone when you see Kaito come up to you wearing a oversized hoodie with a bit of a worried look.

"Have you seen my binder?.. I can find it.." Kaito says is bit nervously and worryingly.
