If I love you, and you happen to love me. When your hair is messy, I will smooth it out for you with a smile, and then I will linger on your hair for a few more seconds. But what if I love you and you unfortunately don't love me. Your hair is messy, I will only tell you gently, your hair is messy. This is probably the purest view of love. If you love each other, you can hold hands until old age; if you miss someone, you can protect him well.
