Why I am not able to do simultaneous requests in Tornado?

Below tornado APP has 2 end points. One(/) is slow because it waits for an IO operation and other(/hello) is fast. My requirement is to make a request to both end points simultaneously.I observed it takes 2nd request only after it finishes the 1st one. Even though It is asynchronous why it is not able to handle both requests at same time ? How to make it to handle simultaneously?

    def get(self):
        self.do_something()
        self.write("FINISHED")
        self.finish()

    def do_something(self):
        inp = input("enter to continue")
        print (inp)
class HelloHandler(tornado.web.RequestHandler):

    def get(self):
        print ("say hello")
        self.write("Hello bro")
        self.finish(

    return tornado.web.Application([
    (r"/", MainHandler),
    (r"/hello", HelloHandler)
])
if __name__ == "__main__":
    app = make_app()
    app.listen(8888)
    tornado.ioloop.IOLoop.current().start()
