In fact, everyone has an angel protecting himself forever.
其实每个人都有一个永远守护着自己的天使
If this angel feels that your life is full of pain and you always feel excessively sad, She would turn into someone else beside you. Maybe it's a friend of you, or your lover, or a net-friend you have never met,or a stranger you just met only once.
这个天使如果觉得你的生活太过痛苦,你的心情太过悲伤,那么她就化身成你身边的某一个人,也许是你的朋友,也许是你的恋人,也许是你未曾见过的网友,也许是你仅仅见过一面的陌生人.
