你会爱上一个人但他们可能不爱你。

You can love someone and them not love you back.

不要误会我-爱上一个人可以给你很多的热情甚至能让你箭步如飞。

Don't get me wrong - falling in love can give you a lot of zest and literally put a spring in your step.

孤单不是与生俱来，而是有你爱上一个人的那一刻开始。

Alone is not born, but you fall in love with a person of the moment.
