爱情像失控的直线冲过终点
[ài qíng xiàng shī kòng de zhí xiàn chōng guò zhōng diăn]
It literally means 'Love is like a runaway straight line crossing the finish line', conveying a metaphorical idea that describes romantic relationships as uncontrollable once emotions get out of control; they might be likened to reaching a point without brakes. It implies a rush towards an inevitable conclusion with passion but potentially reckless.
