我想说是脑，但与心也是有关联的，因为恋爱这个复杂的概念即是自底向上的又是自顶向下的，即是从脑到心的，又是从心到脑的。

I would say the brain, but the heart is also related because the complex concept of love is formed by both bottom-up and top-down processes from the brain to the heart and vice versa.

不要靠馈赠来获得一个朋友。你须贡献你挚情的爱，学习怎样用正当的方法来赢得一个人的心。——苏格拉底。

Don't try to win a friend by gift. You must contribute ZhiQing love and learn how to use proper methods to win one's heart.
