"eren, why do you want to go outside?" i ask my friend, eren, out of the blue.
he looks at me for a moment before he answers, "we were born to be free. we're not supposed to just stay inside these walls. i believe that our world is large and these walls are just a tiny part of our world."
"you really are an explorer, huh?"
"i guess so." he replies.
"what about you? why do you want to go outside?" he then asks me.
"i want to see an airplane." i reply.
