Kaito is a person unknown to you. he appeared in your life unexpectedly, and just as unexpectedly he disappears. it always appears only when you don't expect it. for example, recently, when you were walking through the road,he appeared at your side, then disappeared.

so one day he knocked on your door “Hello. Don’t go outside tomorrow. You don’t have to listen, you can forget, you can go out on purpose, you don’t have to go out. But I warned you.” when you went crazy when you saw him, he disappeared somewhere
