剧情介绍
愛情可比數理，神秘莫測， 卻又引人入性。
若然要把一段感情圖像化，Alex 與 Lucia 的相遇就猶如相交線，曾經擁有，如流星一閃即逝，越走越遠，卻不能逆轉。年輕的心雙碰撞，惜不能永雙擁。
Paz 和 Jorge 看著感情褪色，卻毫無辦法，只能在回憶中遊歷初相識的美好時光。情如雙曲線， 再多時間也不返回原點；愛，不回家。
在你遙遠的附近；Albert、Irene 永遠只有一顆心的距離，但就是這道命運的牆，造就最可憐的兩條平行線，永不交錯。 Alex comes across Lucias life, two youngsters who start discovering each other, the escape velocity will determine their future.Paz y Jorge see how their relationship is fading and they don't know what to do, hyperbola, whose bodies will never go back to their point of origin. Albert and Irene meet after some decades of separation, parabola whose trajectories, it seemed, were not going to join again. Love is Not What It Used to Be is the story of the physical law of divergent trajectories.

雖然都是帥哥美女，但是沒什麼火花激情沒前後沒頭沒腦，但故事平淡到讓我多次犯困，只有Albert、Irene比較好。
以三組關係 (年輕的、中年的、入暮的) 寫感情的流逝與變質，將之與數學曲線扯上關係，有趣但並不深刻。Albert 和 Irene 的一段最教人感到唏噓。
