590일차 오늘으 표현은 None of us~아무도 해당될지않을때 I am sure ~ None of us can solve this problem? None of us remember the actor's name. None of us want to hear your singing. None of us want to lose our money anymore. None of us can drive. I am sure we will win. I am sure he will remember your birthday. I am sure he is an angel.
