One can not only fall in love with one person during his life, there are always different people who are willing to compare with you in different period of time. He might be the person who cares about you in silence when you in gloomy, might be the person who gives you more belief when you in glory, might be the person who was willing to be together with you during the disaster or might be the person who enjoys the happiness with you. In those memories there must be  a person who worth using a life to recall, and there is also one person who you are cherishing by your life.
