爱情中,付出的一方会更加敏感自己的成本投入;接受付出的一方则常常对此浑然不觉。当付出的一方变得不计成本,无欲则刚,接受的那一方就可能变得成本巨大。他是所有追求者中,最不起眼的一个。而她美丽、有才华、心气儿高,不屑于在大学时谈恋爱,因此他只是作为一个坚固的备胎,招之即来,挥之即去。大学毕业,她去北京,他二话不说,跟着去了,初到北京那两年,他们始终没断了联系,她那么寂寞,同时感念于他的忠心,然而他始终不是理想的男朋友。 In love, the one who pays is more sensitive to their own costs; the one who receives the payment is often unaware of it. When paid one becomes out of cost, no desire is just, the one who accepts may become costly. He is one of the most obscure of all suitors. And she is beautiful, talented, high-spirited, disdain to fall in love at college, so he just as a solid spare tire, strokes that come, play that go. After graduating from college, she went to Beijing. After all, he went without saying anything. After he first arrived in Beijing for two years, they never stopped contact. She was so lonely and missed his loyalty. However, he was never an ideal boyfriend.
