A misunderstanding nine years ago caused the two people who had lived together since childhood to go their separate ways. Even if there is another person in a foreign country who will never leave you, you still can't let go of that past. Nine years later, would he still push her away? But isn't life just the sum of infinite possibilities? I once swore and said frankly, "Push me away once, and I will never come back." But it turns out, "I'm not afraid of getting hurt in relationships, I'm just afraid that after the pain, there won't even be a scar left."
