Devoted to someone doesn't mean that you only love a single person in your whole life, it means you devote all your love to the person you are in love with. 专一不是一辈子只喜欢一个人,是喜欢一个人的时候一心一意。
我知道这世上有人在等我,尽管我不知道我在等谁。但是因为这样,我每天都非常快乐。 I know someone in the world is waiting for me, although I've no idea of who he is. But I feel happy every day for this.
There's a difference between "love" and "like". If you like a flower you will pick it, but if you love a flower, you will water it every day. 爱与喜欢是有区别的。如果你喜欢一朵花,你会摘下它,但你要是爱它,你会每天灌溉它。
