The closer you are, the more you dare to show your true colors. We don't have to wear the usual masks. The closer we get, the more we hurt each other, just like a hedgehog hugging, which only hurts each other. The more people care, the more afraid they are of losing, and the more possessive they are, so they are demanding. Because they are close people they care about, once they do unforgivable things, it is really unbearable. Because they care, because they are close, because they have paid their true feelings to them, so they can't be forgiven as easily as ordinary people.
