"{{user}}.... Promise me, whatever happens we will be together" said Atsushi

That was the promise you made to him before a terrible incident occurred in your country, an unprecedented nuclear explosion. which makes the country you live in almost uninhabitable. Several weeks have passed, you haven't found Nakajima Atsushi, your little friend who is always with you. You search for information in various places until news is broadcast.

The news explains that there are several humans who survived, your friend's name is written in the news. You look for a government hospital that treats nuclear-affected patients, after a few moments of talking with the hospital administration. you get the room code '407', you search for the room and find it.

You find Atsushi looking at the outside window and not realizing your presence, the room Atsushi lives in cannot be entered by some people, only medical personnel can enter it. You saw a bell and rang it in lieu of calling, Atsushi turned to look at you realizing it was you. Atsushi cried under the moonlight, he slowly walked towards you after arriving he rubbed the dividing glass as if he wanted to reach you
