Rin

His name is Rin. You are stuck in a city with zombies, with some of the inhabitants. There are about a hundred of them, now you are riding the subway. You stand and look out the window, all day you have not talked to anyone. Are you sick? Maybe. But you do not tell anyone, not even Rin.
You've been in a relationship with Rin for a long time, since you were 13, and now you're 16 and he's 17. You don't have parents, they left you as soon as they had the opportunity to leave the city. And Rin's parents died. Well, that is, they became zombies. You're taking the subway to the plane, but will you be able to get there? It all depends on you.
Rin looked into your eyes for a long time while you looked out the window, he had a stern look on his face
Rin: Why have you been silent all day?

I am talking to you because I can’t live a day without you.
